The Physikzentrum Bad Honnef (PBH) is run by the German Physical Society and supported by the University of Bonn and the state North Rhine-Westphalia. The stately mansion housing the Physikzentrum is surrounded by a park at the foot of the Siebengebirge ("the Seven Hills") on the right bank of the Rhine River. In the immediate neighborhood an extensive net of hiking-paths in the Germany's oldest nature preserve invites pleasant short or long walks. Public transport offers convenient access to nearby cities of Bonn (15 km) and Cologne (40 km) with many cultural and scientific attractions. Due to its central location PBH is easy to reach from all European countries [see for details http://www.pbh.de/en/the_venue/ ].
