Haarberg, Mountain summit in Haaren, Germany.

Haarberg is the highest peak in the Haaren district and stands at 239 meters (784 feet) above sea level. A tall metal cross and a chapel sit at the top, creating a focal point for visitors to the area.

During World War Two, the hill held military importance as American forces moved through the area in late 1944. After the conflict, the summit became a place for religious symbols and spiritual meaning.

The Friedenskapelle (Peace Chapel) near the summit was built in 1969 to plans by the Haaren architect Paul Stollmann. It is a Catholic chapel and stands close to the 1971 metal cross. The hill is part of the local recreation area for Haaren and Verlautenheide.

The Haarberg lies on the northeastern edge of the Aachen basin, reachable on foot from Haaren and Verlautenheide. Paths were upgraded and orchards and biotope areas created during the 2004–2009 ecology project. The 15 m metal cross stands on a round concrete viewing platform at the 239.3 m summit.

The 1971 metal cross has no carvings; the biblical scenes belong to the 1891 brick cross by architect Heinrich van Kann, destroyed in 1944. A 1:10 replica made in 2015 by Franz Josef Heuser and Wilfried Koerens stands in the Akazienstraße in Haaren.
