The University of Bonn does not have a centralized campus. The main building is the "Kurfürstliches Schloss", the former residential palace of the prince-elector of Cologne in the city center. The main building was built by Enrico Zuccalli for the prince-elector of Cologne, Joseph Clemens of Bavaria from 1697 to 1705. Today it houses the faculty of humanities and theology and the university administration. The "Hofgarten", a large park in front of the main building is a popular place for students to meet, study and relax. The Hofgarten was repeatedly the place for political demonstrations as for example the demonstration against the NATO Double-Track Decision on 22 October 1981 with about 250,000 participants.
