A Monument with Strong Character

Alt St. Martin is one of the places where the past can not only be observed, but nearly felt. The church construction began in the 13th century, was later heavily damaged, and has been changed and used repeatedly over the centuries. It is this complexity that makes the place appealing: visitors experience church space, monument preservation, and urban history all in one event.
