At the Petersberg site, you can experience the eventful history of the site in an authentic setting. The visitor center, which consists of five areas, is located at the driveway to the building complex. It is home to a unique exhibition. The journey ranges from Konrad Adenauer's legendary "carpet scene" to the state visits of the economic miracle era and the Afghanistan conferences shortly after the turn of the millennium. In addition, one part of the exhibition looks at the nature of the Petersberg. Another focuses on the building's former function as a guardhouse and its security equipment.

This unusual building, erected between 1882 and 1884 for the Bonn innkeeper's son Stephan von Sarter, is one of the most important palace buildings of the late 19th century in Germany.
