Haus Laach

Haus Laach is a castle ruin in Bergheim with partially preserved cellar vaults and a Gothic gate arch from the 16th century. The remains lie hidden within dense vegetation between the towns of Thorr, Ahe, and Elsdorf-Widdendorf.

The property was first documented in 1246 as a knight's castle and served for centuries as a border post in the Erft lowlands. It was inhabited by several noble families over the centuries before being abandoned in 1918.

The castle represented the only known half-timbered fortress in the Rhein-Erft district, featuring a private chapel within a small bay window of the manor house.

The site is difficult to access as the remains are surrounded by dense vegetation and no marked path leads to the location. It is best visited during summer when the vegetation is less dense and visibility is better.

The castle was constructed with oak timber in Gothic style and was the only known half-timbered fortress in the Rhein-Erft district. The construction demonstrates the influence of regional building techniques that were unusual for fortifications in the area.
