Klosterruine Heisterbach / Petersberg

Hotel Petersberg is a hotel and official guest house of the Federal Republic of Germany, termed the "Bundesgästehaus" (the official title being Gästehaus der Verfassungsorgane der Bundesrepublik Deutschland). It is located on the Petersberg, a prominent mountain of the Siebengebirge near Bonn, Germany.

The Petersberg (331 metres (1,086 ft)), formerly known as the Stromberg, is a mountain in the Siebengebirge mountain range near Bonn, Germany. It overlooks the cities of Königswinter, on the right bank of the Rhine river, and Bonn on the opposite side. Today the peak is the site of the Hotel Petersberg, which serves as a guest house of the Federal Republic of Germany.

Heisterbach Abbey (Kloster Heisterbach; also Petersthal, formerly Petersberg) was a Cistercian monastery in the Siebengebirge near Oberdollendorf in North Rhine-Westphalia, Germany.
