Haus Anger, Manor house in Ratingen, Germany.

Haus Anger is a former knight's estate in the Angertal valley near Ratingen, made up of a defensive main building of rubble stone with a steep hipped roof. Its asymmetric windows set at different heights and irregular masonry point to many rebuilds around a core held to be a 12th-century residential tower. Farm buildings frame it, and traces of the water-filled moats that once enclosed the estate remain visible.

Haus Anger was first documented as angeron curtis in 904. In 1148 it passed to the imperial abbey of Werden as curtim que dicitur Angera, which granted it to its ministeriales. It is unclear whether it was slighted after the 1288 Battle of Worringen, since the peace treaty barred Cologne from building fortifications on the Anger. By 1461 it had become an ordinary farm estate.

The estate demonstrates how wealthy families once lived in the region and designed their homes as symbols of their social standing. The way it was built reflects the tastes and practices that were common among landowners of that era.

Haus Anger lies in the Angertal valley between Ratingen and Heiligenhaus, not in the town centre, within a nature reserve. It stands in a broad valley meadow at an old crossing of the Angerbach, framed by the Angermühle and the Angerforsthaus. The ensemble is a popular local recreation destination, so expect paths through the protected valley rather than urban streets.

The 1288 Treaty of Worringen barred the Cologne archbishop from building fortifications along the Anger, so it is unclear whether Haus Anger was slighted then. The estate appears as a farm from 1461, and the main building was only extensively restored in 2013 after years of neglect.
