Hardtberg-Gymnasium Bonn | Address & Open House Day
The Hardtberg-Gymnasium Bonn is a school that can often be found online through individual search terms, but is understood in practice only through its overall picture. It is a four-stream gymnasium under the public sponsorship of the city of Bonn, founded in 1966, located in the Brüser Berg district in the Hardtberg borough. The school describes itself as an important reference point for cultural and educational life in the area and refers to around 950 students and about 80 teachers. Thus, the HBG is not an anonymous large school, but a manageable, clearly profiled place of learning with several focal points, a well-visible structure, and a very active school life. Those looking for address, secretariat, faculty, dates, or open house day will find here a school that prepares its information transparently, up-to-date, and service-oriented. ([hardtberg-gymnasium.de](https://hardtberg-gymnasium.de/wp-content/uploads/2023/10/HBG-Schulprogramm-2023-Endfassung-2023-10-17.pdf))
Especially for a school like the Hardtberg-Gymnasium Bonn, the most common search queries are very practical: Where is the building located exactly, when is the secretariat reachable, what dates are upcoming, and what does the profile look like? The official website answers these questions not with promotional language, but with clear facts about administration, classes, focal points, and activities. At the same time, the website shows that the HBG is much more than just a place for lessons. There are indications of care, self-learning center, artistic and scientific offerings, a bilingual branch, and many current news from school life. This mix makes the Hardtberg-Gymnasium Bonn particularly relevant for parents, future students, alumni, and interested parties. ([hardtberg-gymnasium.de](https://hardtberg-gymnasium.de/wir/))
Address, Secretariat, and Accessibility
The most important orientation for anyone wishing to visit or contact the Hardtberg-Gymnasium Bonn is the address at Gaußstraße 1, 53125 Bonn. The school is located in the residential area of Brüser Berg and thus in a part of Bonn that is perceived as a fixed reference point of the Hardtberg borough. According to the school profile, the HBG is very well connected to the surrounding districts and municipalities by several bus lines of public transport, which makes the journey to school easier for families from Bonn and the surrounding area. Therefore, those looking for the exact location will find a classic Bonn school address, but at the same time a location that is embedded in the everyday life of the district and does not only function as a building complex. ([hardtberg-gymnasium.de](https://hardtberg-gymnasium.de/))
For direct contact, the secretariat is one of the most important points of contact. The website clearly displays the administration, including phone and email address. The secretariat can be reached at +49 (0)228 / 77 73 30, and the general email address is verwaltung@hardtberg-gymnasium.de. The opening hours are Monday to Thursday from 7:45 AM to 2:45 PM and Friday from 7:45 AM to 1:00 PM. This is particularly helpful for parents who have questions about registration, deadlines, or organizational issues. The contact pages of the faculty and school management also show that the HBG relies on clear responsibilities and not on hidden contact paths. Therefore, those who call or write will land directly with the official school administration. ([hardtberg-gymnasium.de](https://hardtberg-gymnasium.de/impressum-datenschutz/))
However, practical accessibility does not end with the address and phone. The school profile emphasizes that the Hardtberg-Gymnasium is a half-day gymnasium that also offers midday and homework supervision. This is important for families because school is not only seen as a place for lessons but as an organized daily framework. This is also reflected in the transparent presentation of various contacts, such as for the introductory phase, middle school, upper school, bilingual branch, and digital development. The website thus conveys a well-structured impression that provides orientation, especially during initial contact and registration. Therefore, those who want to find their way quickly before a visit receive not only an address but also a functioning contact and service concept. ([hardtberg-gymnasium.de](https://hardtberg-gymnasium.de/wp-content/uploads/2023/10/HBG-Schulprogramm-2023-Endfassung-2023-10-17.pdf))
Open House Day, Dates, and Photos
A central search topic around the Hardtberg-Gymnasium Bonn is the open house day. The school announces that this event traditionally takes place in the fall, usually in September or October, and is announced in advance on the homepage as well as in the elementary schools. For 2026, October 10 is already mentioned on the homepage. This makes it clear that the HBG not only manages current dates but actively communicates them. For those interested in the school, this provides early planning security. This is especially crucial for parents of fourth graders, as the transition from elementary school to a gymnasium is often associated with many questions. ([hardtberg-gymnasium.de](https://hardtberg-gymnasium.de/erprobungsstufe/))
The content orientation of the open house day shows how the HBG makes its focal points tangible. In the described program, visitors were welcomed by the principal, after which children and parents could participate in class offerings in French, German, computer science, math, geography, English, and art. This was complemented by tours of the school building, information stands on the bilingual branch, artistic focus, midday care, and working groups, as well as hands-on activities such as experimenting, microscopy, and movement games. This is exactly the kind of event that not only informs but makes a school tangible. Those looking for photos or images will find the best access in this: The HBG presents itself through real insights into lessons, rooms, and everyday life. ([hardtberg-gymnasium.de](https://hardtberg-gymnasium.de/tag-der-offenen-tuer-am-hbg/))
Current news on the homepage also shows that school life at the HBG is told in a strongly visual and eventful manner. There are contributions about summer concerts, a podium debate as part of the 60th school anniversary, a talent day, a successful exchange trip to Alsace, and a MINT-EC camp on the topic of insects. This mix of music, language, science, and encounters conveys a lively picture of the school. Therefore, those looking for photos, images, or current impressions do not have to rely on a single gallery but can dive directly into school life through the news. For search queries related to dates and images, the HBG is thus very well positioned. ([hardtberg-gymnasium.de](https://hardtberg-gymnasium.de/))
Faculty, School Management, and Personal Contacts
The Hardtberg-Gymnasium Bonn publishes a detailed faculty list on its website and places great value on transparency. According to the school profile, about 80 teachers work at the school, which fits the four-stream gymnasium and the size of the location. On the contact pages, school management, deputy school management, secretariat, building management, and other responsibilities are clearly separated. Among others, the principal Günther Schlag and the deputy principal Maja Taraš-Meštrović are mentioned. This is helpful for parents and students because they can quickly see who is responsible for which questions. The HBG thus does not appear as a faceless institution but as a school with clear contacts and understandable paths. ([hardtberg-gymnasium.de](https://hardtberg-gymnasium.de/wir/))
Particularly striking is the differentiated structure of the extended school management. There are, among other things, coordinations for the introductory phase, middle school, upper school, bilingual branch, school and teaching development, and digitalization. This division shows that the HBG is not only managed but pedagogically organized. Therefore, those searching for the faculty will find not only names but also subject-specific responsibilities. This is logical for a school with so many profile areas, as bilingual instruction, digital media, talent promotion, and transitions between levels require different support. The contact page thus conveys a picture of professionalism and specialization without becoming confusing. ([hardtberg-gymnasium.de](https://hardtberg-gymnasium.de/wir/))
Additionally, a dense circle of counseling and communication is part of school life. The website explains that the HBG school planner not only serves as a homework diary but also contains information about mediators, counseling teachers, school emergency services, and working groups. It is mandatory for grades 5 to 10 and facilitates communication between home and school by centralizing excuses and organizational information. This is complemented by contacts for school career counseling, individual support, and special talents. Thus, a faculty is created that not only teaches but also accompanies in everyday life. This is particularly relevant for search queries like faculty, secretariat, or dates. ([hardtberg-gymnasium.de](https://hardtberg-gymnasium.de/schulplaner/))
Bilingual Branch, MINT, and Artistic Focus
The perhaps strongest profile area of the Hardtberg-Gymnasium Bonn is the bilingual German-French branch. According to the school program, the HBG has been one of the first gymnasiums in North Rhine-Westphalia to establish such a branch since 1970. In the bilingual classes, French is taught from grade 5 with an increased weekly hour count alongside English. In the non-bilingual classes, French begins as a second foreign language from grade 7, and later Spanish can be added in the upper school. Additionally, the school points out that the bilingual branch can be completed with AbiBac or CertiLingua. This makes the HBG particularly attractive for families who want to combine international orientation, language competence, and school continuity. ([hardtberg-gymnasium.de](https://hardtberg-gymnasium.de/wp-content/uploads/2023/10/HBG-Schulprogramm-2023-Endfassung-2023-10-17.pdf))
The mathematical and scientific area is also strongly represented at the HBG. Since 2011, the school has been a MINT-EC school, thus part of a nationwide excellence network for particularly engaged mathematical and scientific schools. The MINT profile is evident not only in lessons but also in projects, competitions, and collaborations. On the school grounds, there is a large school garden with a biotope, wild bee house, and beds that are worked on by students. In the computer science area, there has been a homepage working group for years that later developed into the student company ITSS. Additionally, there are regular competitions in mathematics, physics, chemistry, and biology, as well as collaborations with Bonn city utilities, DLR, Bonn-Rhein-Sieg University, and the research institute caesar. This is a clearly recognizable focus with real subject depth. ([hardtberg-gymnasium.de](https://hardtberg-gymnasium.de/mint/))
The artistic area is also part of the profile, which is evident in wind classes, music ensembles, and regular performances. The school program explicitly names this area as one of the three subject focuses that allow for individual profile development. The current news on the homepage with summer concerts and musical contributions shows that this focus is not just on paper but becomes visible during the school year. Thus, a coherent overall picture emerges from language, science, and music. For search terms like reviews, ratings, or photos, this is interesting in that the HBG should not be defined by general keywords but by concrete offerings, subject profiles, and lively practice. This is exactly where the strength of this school lies. ([hardtberg-gymnasium.de](https://hardtberg-gymnasium.de/wp-content/uploads/2023/10/HBG-Schulprogramm-2023-Endfassung-2023-10-17.pdf))
Facilities, Supervision, and School Life
The Hardtberg-Gymnasium Bonn has facilities that are geared towards modern school operations. The school program speaks of bright, modernized, and generously furnished classrooms and specialized rooms in three interconnected building parts. Interactive whiteboards or digital board systems are used there. Additionally, there is a self-learning center with a presence library and several computer workstations, as well as a school library for lending. For larger school events, an auditorium and the auditorium in the Educational Center across the street are available. The school is also well-equipped for sports: in addition to its own gym, the Hardtberghalle, two sports fields, and the Hardtbergbad can be used. This makes it clear that the HBG offers not only classrooms but a real learning and living environment. ([hardtberg-gymnasium.de](https://hardtberg-gymnasium.de/wp-content/uploads/2023/10/HBG-Schulprogramm-2023-Endfassung-2023-10-17.pdf))
Also outside the classic subject rooms, school life at the HBG is well organized. The schoolyard is spacious and partially greened, there is a break hall, the roof under an air bridge as a shelter in the rain, and at the back a large school garden with a green classroom, planting area, and pond. The midday supervision offers a playroom for younger grades and further leisure opportunities for older students. According to the school program, grades 5 to 8 currently use this supervision on a voluntary basis. This is important for families because the school thus offers not only lessons but also reliable structures in the afternoon. Those looking for a school with practical everyday organization will find a very clear plus here. ([hardtberg-gymnasium.de](https://hardtberg-gymnasium.de/wp-content/uploads/2023/10/HBG-Schulprogramm-2023-Endfassung-2023-10-17.pdf))
The everyday structure also includes a pedagogically well-thought-out introduction to the school. In the introductory phase, not only the core subjects are taught, but also digital media competence, learning methods, and social learning are specifically promoted. The school works with media scouts, the program Seelenschlau, method days for learning how to learn, and digital media as well as Lions Quest. Additionally, there are experience-oriented events such as the joint trip of all fifth grades to the LVR open-air museum in Kommern and a subsequent picnic with parents on the school grounds. Exactly such elements make school life at the HBG tangible: it is not only about lessons but about transitions, community, and orientation. ([hardtberg-gymnasium.de](https://hardtberg-gymnasium.de/erprobungsstufe/))
History, Alumni, and What Shapes the HBG
The history of the Hardtberg-Gymnasium Bonn is closely linked to the borough. According to the school profile, the school was founded in 1966 and was thus the youngest gymnasium in the Hardtberg borough. The website also points out that the HBG celebrated its 50th anniversary in 2016. In 2026, the 60th school anniversary will add another milestone, which the school also makes visible in current contributions. Those searching for the keyword alumni will quickly realize: the HBG is not a school without a past, but an institution whose development has grown with the district over decades. This historical depth makes it particularly interesting for search queries related to school, history, and alumni. ([hardtberg-gymnasium.de](https://hardtberg-gymnasium.de/wp-content/uploads/2023/10/HBG-Schulprogramm-2023-Endfassung-2023-10-17.pdf))
Former students are also part of this school identity. According to the website, the HBG support association consists not only of parents but also of former students. It supports events such as theater performances and concerts as well as teaching and learning materials that the school could not provide to this extent otherwise. This shows a special continuity: those who have left the HBG often remain connected to the school. This fits with a gymnasium that focuses on community, support, and long-term bonds. For search terms like alumni or reviews, this is important because the school itself emphasizes active participation, support, and connectedness rather than pure external evaluation. ([hardtberg-gymnasium.de](https://hardtberg-gymnasium.de/wir/))
Those who visit the Hardtberg-Gymnasium website today get a picture of a school that has grown historically, is organizationally clear, and is broadly positioned in content. Bilingual instruction, MINT-EC, music, supervision, career orientation, collaborations with the University of Bonn, and a vibrant news culture belong together here. This also explains why so many different search queries target the HBG: from photos and images to secretariat and dates to faculty and open house day. The Hardtberg-Gymnasium Bonn is indeed not just an address but a school location with profile, history, and a very active present. ([hardtberg-gymnasium.de](https://hardtberg-gymnasium.de/wir/))

Hardtberg-Gymnasium Bonn | Address & Open House Day
The Hardtberg-Gymnasium Bonn is a school that can often be found online through individual search terms, but is understood in practice only through its overall picture. It is a four-stream gymnasium under the public sponsorship of the city of Bonn, founded in 1966, located in the Brüser Berg district in the Hardtberg borough. The school describes itself as an important reference point for cultural and educational life in the area and refers to around 950 students and about 80 teachers. Thus, the HBG is not an anonymous large school, but a manageable, clearly profiled place of learning with several focal points, a well-visible structure, and a very active school life. Those looking for address, secretariat, faculty, dates, or open house day will find here a school that prepares its information transparently, up-to-date, and service-oriented. ([hardtberg-gymnasium.de](https://hardtberg-gymnasium.de/wp-content/uploads/2023/10/HBG-Schulprogramm-2023-Endfassung-2023-10-17.pdf))
Especially for a school like the Hardtberg-Gymnasium Bonn, the most common search queries are very practical: Where is the building located exactly, when is the secretariat reachable, what dates are upcoming, and what does the profile look like? The official website answers these questions not with promotional language, but with clear facts about administration, classes, focal points, and activities. At the same time, the website shows that the HBG is much more than just a place for lessons. There are indications of care, self-learning center, artistic and scientific offerings, a bilingual branch, and many current news from school life. This mix makes the Hardtberg-Gymnasium Bonn particularly relevant for parents, future students, alumni, and interested parties. ([hardtberg-gymnasium.de](https://hardtberg-gymnasium.de/wir/))
Address, Secretariat, and Accessibility
The most important orientation for anyone wishing to visit or contact the Hardtberg-Gymnasium Bonn is the address at Gaußstraße 1, 53125 Bonn. The school is located in the residential area of Brüser Berg and thus in a part of Bonn that is perceived as a fixed reference point of the Hardtberg borough. According to the school profile, the HBG is very well connected to the surrounding districts and municipalities by several bus lines of public transport, which makes the journey to school easier for families from Bonn and the surrounding area. Therefore, those looking for the exact location will find a classic Bonn school address, but at the same time a location that is embedded in the everyday life of the district and does not only function as a building complex. ([hardtberg-gymnasium.de](https://hardtberg-gymnasium.de/))
For direct contact, the secretariat is one of the most important points of contact. The website clearly displays the administration, including phone and email address. The secretariat can be reached at +49 (0)228 / 77 73 30, and the general email address is verwaltung@hardtberg-gymnasium.de. The opening hours are Monday to Thursday from 7:45 AM to 2:45 PM and Friday from 7:45 AM to 1:00 PM. This is particularly helpful for parents who have questions about registration, deadlines, or organizational issues. The contact pages of the faculty and school management also show that the HBG relies on clear responsibilities and not on hidden contact paths. Therefore, those who call or write will land directly with the official school administration. ([hardtberg-gymnasium.de](https://hardtberg-gymnasium.de/impressum-datenschutz/))
However, practical accessibility does not end with the address and phone. The school profile emphasizes that the Hardtberg-Gymnasium is a half-day gymnasium that also offers midday and homework supervision. This is important for families because school is not only seen as a place for lessons but as an organized daily framework. This is also reflected in the transparent presentation of various contacts, such as for the introductory phase, middle school, upper school, bilingual branch, and digital development. The website thus conveys a well-structured impression that provides orientation, especially during initial contact and registration. Therefore, those who want to find their way quickly before a visit receive not only an address but also a functioning contact and service concept. ([hardtberg-gymnasium.de](https://hardtberg-gymnasium.de/wp-content/uploads/2023/10/HBG-Schulprogramm-2023-Endfassung-2023-10-17.pdf))
Open House Day, Dates, and Photos
A central search topic around the Hardtberg-Gymnasium Bonn is the open house day. The school announces that this event traditionally takes place in the fall, usually in September or October, and is announced in advance on the homepage as well as in the elementary schools. For 2026, October 10 is already mentioned on the homepage. This makes it clear that the HBG not only manages current dates but actively communicates them. For those interested in the school, this provides early planning security. This is especially crucial for parents of fourth graders, as the transition from elementary school to a gymnasium is often associated with many questions. ([hardtberg-gymnasium.de](https://hardtberg-gymnasium.de/erprobungsstufe/))
The content orientation of the open house day shows how the HBG makes its focal points tangible. In the described program, visitors were welcomed by the principal, after which children and parents could participate in class offerings in French, German, computer science, math, geography, English, and art. This was complemented by tours of the school building, information stands on the bilingual branch, artistic focus, midday care, and working groups, as well as hands-on activities such as experimenting, microscopy, and movement games. This is exactly the kind of event that not only informs but makes a school tangible. Those looking for photos or images will find the best access in this: The HBG presents itself through real insights into lessons, rooms, and everyday life. ([hardtberg-gymnasium.de](https://hardtberg-gymnasium.de/tag-der-offenen-tuer-am-hbg/))
Current news on the homepage also shows that school life at the HBG is told in a strongly visual and eventful manner. There are contributions about summer concerts, a podium debate as part of the 60th school anniversary, a talent day, a successful exchange trip to Alsace, and a MINT-EC camp on the topic of insects. This mix of music, language, science, and encounters conveys a lively picture of the school. Therefore, those looking for photos, images, or current impressions do not have to rely on a single gallery but can dive directly into school life through the news. For search queries related to dates and images, the HBG is thus very well positioned. ([hardtberg-gymnasium.de](https://hardtberg-gymnasium.de/))
Faculty, School Management, and Personal Contacts
The Hardtberg-Gymnasium Bonn publishes a detailed faculty list on its website and places great value on transparency. According to the school profile, about 80 teachers work at the school, which fits the four-stream gymnasium and the size of the location. On the contact pages, school management, deputy school management, secretariat, building management, and other responsibilities are clearly separated. Among others, the principal Günther Schlag and the deputy principal Maja Taraš-Meštrović are mentioned. This is helpful for parents and students because they can quickly see who is responsible for which questions. The HBG thus does not appear as a faceless institution but as a school with clear contacts and understandable paths. ([hardtberg-gymnasium.de](https://hardtberg-gymnasium.de/wir/))
Particularly striking is the differentiated structure of the extended school management. There are, among other things, coordinations for the introductory phase, middle school, upper school, bilingual branch, school and teaching development, and digitalization. This division shows that the HBG is not only managed but pedagogically organized. Therefore, those searching for the faculty will find not only names but also subject-specific responsibilities. This is logical for a school with so many profile areas, as bilingual instruction, digital media, talent promotion, and transitions between levels require different support. The contact page thus conveys a picture of professionalism and specialization without becoming confusing. ([hardtberg-gymnasium.de](https://hardtberg-gymnasium.de/wir/))
Additionally, a dense circle of counseling and communication is part of school life. The website explains that the HBG school planner not only serves as a homework diary but also contains information about mediators, counseling teachers, school emergency services, and working groups. It is mandatory for grades 5 to 10 and facilitates communication between home and school by centralizing excuses and organizational information. This is complemented by contacts for school career counseling, individual support, and special talents. Thus, a faculty is created that not only teaches but also accompanies in everyday life. This is particularly relevant for search queries like faculty, secretariat, or dates. ([hardtberg-gymnasium.de](https://hardtberg-gymnasium.de/schulplaner/))
Bilingual Branch, MINT, and Artistic Focus
The perhaps strongest profile area of the Hardtberg-Gymnasium Bonn is the bilingual German-French branch. According to the school program, the HBG has been one of the first gymnasiums in North Rhine-Westphalia to establish such a branch since 1970. In the bilingual classes, French is taught from grade 5 with an increased weekly hour count alongside English. In the non-bilingual classes, French begins as a second foreign language from grade 7, and later Spanish can be added in the upper school. Additionally, the school points out that the bilingual branch can be completed with AbiBac or CertiLingua. This makes the HBG particularly attractive for families who want to combine international orientation, language competence, and school continuity. ([hardtberg-gymnasium.de](https://hardtberg-gymnasium.de/wp-content/uploads/2023/10/HBG-Schulprogramm-2023-Endfassung-2023-10-17.pdf))
The mathematical and scientific area is also strongly represented at the HBG. Since 2011, the school has been a MINT-EC school, thus part of a nationwide excellence network for particularly engaged mathematical and scientific schools. The MINT profile is evident not only in lessons but also in projects, competitions, and collaborations. On the school grounds, there is a large school garden with a biotope, wild bee house, and beds that are worked on by students. In the computer science area, there has been a homepage working group for years that later developed into the student company ITSS. Additionally, there are regular competitions in mathematics, physics, chemistry, and biology, as well as collaborations with Bonn city utilities, DLR, Bonn-Rhein-Sieg University, and the research institute caesar. This is a clearly recognizable focus with real subject depth. ([hardtberg-gymnasium.de](https://hardtberg-gymnasium.de/mint/))
The artistic area is also part of the profile, which is evident in wind classes, music ensembles, and regular performances. The school program explicitly names this area as one of the three subject focuses that allow for individual profile development. The current news on the homepage with summer concerts and musical contributions shows that this focus is not just on paper but becomes visible during the school year. Thus, a coherent overall picture emerges from language, science, and music. For search terms like reviews, ratings, or photos, this is interesting in that the HBG should not be defined by general keywords but by concrete offerings, subject profiles, and lively practice. This is exactly where the strength of this school lies. ([hardtberg-gymnasium.de](https://hardtberg-gymnasium.de/wp-content/uploads/2023/10/HBG-Schulprogramm-2023-Endfassung-2023-10-17.pdf))
Facilities, Supervision, and School Life
The Hardtberg-Gymnasium Bonn has facilities that are geared towards modern school operations. The school program speaks of bright, modernized, and generously furnished classrooms and specialized rooms in three interconnected building parts. Interactive whiteboards or digital board systems are used there. Additionally, there is a self-learning center with a presence library and several computer workstations, as well as a school library for lending. For larger school events, an auditorium and the auditorium in the Educational Center across the street are available. The school is also well-equipped for sports: in addition to its own gym, the Hardtberghalle, two sports fields, and the Hardtbergbad can be used. This makes it clear that the HBG offers not only classrooms but a real learning and living environment. ([hardtberg-gymnasium.de](https://hardtberg-gymnasium.de/wp-content/uploads/2023/10/HBG-Schulprogramm-2023-Endfassung-2023-10-17.pdf))
Also outside the classic subject rooms, school life at the HBG is well organized. The schoolyard is spacious and partially greened, there is a break hall, the roof under an air bridge as a shelter in the rain, and at the back a large school garden with a green classroom, planting area, and pond. The midday supervision offers a playroom for younger grades and further leisure opportunities for older students. According to the school program, grades 5 to 8 currently use this supervision on a voluntary basis. This is important for families because the school thus offers not only lessons but also reliable structures in the afternoon. Those looking for a school with practical everyday organization will find a very clear plus here. ([hardtberg-gymnasium.de](https://hardtberg-gymnasium.de/wp-content/uploads/2023/10/HBG-Schulprogramm-2023-Endfassung-2023-10-17.pdf))
The everyday structure also includes a pedagogically well-thought-out introduction to the school. In the introductory phase, not only the core subjects are taught, but also digital media competence, learning methods, and social learning are specifically promoted. The school works with media scouts, the program Seelenschlau, method days for learning how to learn, and digital media as well as Lions Quest. Additionally, there are experience-oriented events such as the joint trip of all fifth grades to the LVR open-air museum in Kommern and a subsequent picnic with parents on the school grounds. Exactly such elements make school life at the HBG tangible: it is not only about lessons but about transitions, community, and orientation. ([hardtberg-gymnasium.de](https://hardtberg-gymnasium.de/erprobungsstufe/))
History, Alumni, and What Shapes the HBG
The history of the Hardtberg-Gymnasium Bonn is closely linked to the borough. According to the school profile, the school was founded in 1966 and was thus the youngest gymnasium in the Hardtberg borough. The website also points out that the HBG celebrated its 50th anniversary in 2016. In 2026, the 60th school anniversary will add another milestone, which the school also makes visible in current contributions. Those searching for the keyword alumni will quickly realize: the HBG is not a school without a past, but an institution whose development has grown with the district over decades. This historical depth makes it particularly interesting for search queries related to school, history, and alumni. ([hardtberg-gymnasium.de](https://hardtberg-gymnasium.de/wp-content/uploads/2023/10/HBG-Schulprogramm-2023-Endfassung-2023-10-17.pdf))
Former students are also part of this school identity. According to the website, the HBG support association consists not only of parents but also of former students. It supports events such as theater performances and concerts as well as teaching and learning materials that the school could not provide to this extent otherwise. This shows a special continuity: those who have left the HBG often remain connected to the school. This fits with a gymnasium that focuses on community, support, and long-term bonds. For search terms like alumni or reviews, this is important because the school itself emphasizes active participation, support, and connectedness rather than pure external evaluation. ([hardtberg-gymnasium.de](https://hardtberg-gymnasium.de/wir/))
Those who visit the Hardtberg-Gymnasium website today get a picture of a school that has grown historically, is organizationally clear, and is broadly positioned in content. Bilingual instruction, MINT-EC, music, supervision, career orientation, collaborations with the University of Bonn, and a vibrant news culture belong together here. This also explains why so many different search queries target the HBG: from photos and images to secretariat and dates to faculty and open house day. The Hardtberg-Gymnasium Bonn is indeed not just an address but a school location with profile, history, and a very active present. ([hardtberg-gymnasium.de](https://hardtberg-gymnasium.de/wir/))
