Wachtberg () is a municipality in the Rhein-Sieg district, of North Rhine-Westphalia, Germany. It is situated approximately 15 km south of Bonn. In December 2025 the Wachtberg municipality had 20,230 inhabitants.
Geology
Geological situation Wachtberg is located on the left bank of the Rhine between the Kottenforst forest to the north, the Voreifel to the west, the lower Middle Rhine Valley to the east and the Ahrgebirge to the south. The municipality was named after one of its highest points, the Wachtberg, located between Berkum and Villip (extinct for 25 million years, now with a height of 258 m).
Political division The municipality was formed in 1969 with the Bonn Act (formally Gesetz zur kommunalen Neugliederung des Raumes Bonn, abbreviated as the "Bonn-Gesetz") and merged 13 now incorporated villages:
Adendorf (with Klein-Villip) Arzdorf Berkum Fritzdorf Gimmersdorf Holzem Ließem Niederbachem Oberbachem (with Kürrighoven) Pech Villip (with Villiprott) Werthhoven Züllighoven
Until then, most of the villages belonged to the so-called "Amt Villip"; Adendorf, Arzdorf and Fritzdorf were added to the newly founded municipality by the town of Meckenheim. Niederbachem is the biggest village within Wachtberg with 4276 inhabitants (July 2018).
The town-hall is in the village of Berkum, approximately in the center of the area. The Rodderberg mountain is in the east of the Wachtberg district.
