Burg Randeck, Medieval castle ruins in Mannweiler-Cölln, Germany.

Burg Randeck is a ruined hill castle on the Schlossberg at 263 m above sea level, west of Mannweiler-Cölln on the Alsenz. Surviving are remnants of the enceinte, a corner outwork, the flanking towers and the foundations of the bergfried.

The castle was first mentioned in 1202 under Henry of Randeck and remained the seat of various noble families for over 5 centuries. In 1690, French troops destroyed the fortification during a succession conflict.

The castle served as the seat of noble families who shaped the region for centuries. Today, visitors can explore the remaining structures and connect with the medieval ruling history of the Alsenz valley.

Access to the ruins is via marked hiking paths that become more demanding on steeper slopes. The terrain is not suitable for visitors with limited mobility, though the paths themselves are relatively easy to follow.

The castle passed in 1668 to Nikolaus Georg Reigersberg, chancellor of Electoral Mainz, after the Lewenstein family died out. In 1844 it was reported as private property, torn down and its stone reused. The Cultural History Society of Mannweiler-Cölln now owns the site.
