A Monument of the Early Federal Republic Opens Its Doors
On September 13, 2026, the Sep-Ruf-Bau in Bonn invites you to the Day of Open Monuments. The house of the German Foundation for Monument Protection is considered a significant testimony of post-war modernism and stands for that light, transparent architecture that made Sep Ruf a key figure in modern construction.

Architecture as Cultural Memory
The three-story reinforced concrete skeleton building was built in 1954/55 as the former Bavarian State Representation and was placed under monument protection in 2002. Its lightness, clear lines, and open spatial effect make the building a vibrant lesson in architectural history to this day.

An Artistic Experience in the Name of Monument Protection
During the visit, guests encounter not only an important building but also an attitude: monument protection as cultural education, as a contemplation of space, material, and light. The Sep-Ruf-Bau exemplifies the early Federal Republic and its search for a modern, democratic visual language.
