Ahornstraße 15a

Ahornstraße 15a is a two-story villa in Steglitz-Zehlendorf with a single-story extension, plastered facade, and round windows on the first floor that have been bricked up. The building, vacant since 2013, contains a basement with former performance spaces and rehearsal rooms for musical activities.

During the Weimar Republic, this building served as the main meeting point for the Social Democratic Party and Reichsbanner to organize resistance against the National Socialists. After the war, it housed the Grand National Mother Lodge between 1946 and 1957 before becoming a cultural venue for young people.

From 1960 to 2010, this building was West Berlin's first youth club and music venue where progressive rock bands performed and young people gathered. The place shaped a generation of music fans and artists in the divided city.

The building is visible from the street but cannot be entered as it has been vacant for years. It is worth observing the facade and characteristic details like the bricked-up windows from the outside.

The facade displays a 'Humanitati' inscription, a remnant from when the masonic lodge occupied the building. This detail marks an important chapter of Berlin's cultural history that visitors often overlook.
