A part of the ministry is based in Berlin-Mitte. When the Bundestag and government moved to Berlin in 1999 the BMA moved into buildings in the Jägerstraße/ Wilhelmstraße. A large part of the ministry stayed in Bonn. Originally the building at Wilhelmstraße 49 was a stately home. After 1826 it was used by the Hohenzollern Prince Karl.
