Haus Böckum, Water castle in Huckingen, Duisburg, Germany

Haus Böckum is a water castle near Duisburg built with fortified walls and surrounded by moats and waterways. The complex includes multiple structures arranged to create a defensive compound that was also designed as a residential space for its owners.

Haus Böckum was first mentioned in 1345 as Thyderich van den Boken, identified as Dietrich von Rheinheim. In 1405 Cologne mercenaries destroyed the castle during the Kalkum feuds. From about 1440 to 1760 the lords of Buer held it, and the east wing with its tower and stone bridge replaced a drawbridge in 1661.

The name Böckum comes from "Hof zu den Buchen" (farm by the beeches), after the beech forest that once reached the site and of which only the Duisburg city forest remains. The lords of Böckum also held the Stroetrecht, the right to keep wild horses in the forest, shared with only a few knightly estates such as Heltorf and Broich.

The grounds are fenced off and entry is prohibited, so the complex can only be viewed from outside. The brick bridge and the east wing with its tower are the oldest parts and face the former moat. The city has opened an enforcement case against the owner over the building's decay, and the property is up for sale.

Haus Böckum held the Stroetrecht, the right to keep wild horses in the forest, a privilege shared with the Duke of Berg by only a few knightly seats such as Heltorf, Broich and Landsberg.
