Burg Bocholt, Medieval castle in Nettetal, Germany

Burg Bocholt is a castle in Nettetal featuring a prominent four-story tower called the Kaiserturm, with stone walls dating to the 14th century. The structure preserves medieval architectural details and now functions as a venue with multiple halls for various gatherings.

The 1096 mention of a "Burg Bocholtz" likely refers to a different site in present-day Belgium, not this castle. The name "Gerald de Bocholt" appears in 1242, starting the noble family that held the castle as a fief of Guelders and guarded the old Roman road. In 1358 the castle was enlarged into a fortress, and in 1450 a gatehouse with courtyard was added. The main castle was probably destroyed during the Seven Years' War (1756–1763) and was not rebuilt.

The Knights' Hall within Burg Bocholt displays vaulted ceilings and historical details, offering space for ceremonies and celebrations for up to 130 guests.

The castle lies in a basin-like terrain about 200 metres long and 150 metres wide, surrounded by two moats that are fully preserved on the west and south sides, plus an earthen rampart. The site is used for events; the gatehouse and courtyard buildings were renovated from 2000 to 2003. Access is generally limited to booked events.

The 21.5-metre Kaiserturm collapsed in 1905, leaving only a fragment of wall; the four-storey brick tower had 2-metre-thick walls and stood on a 7.4-metre square plan. Its first floor held the castle chapel with a cross-vault of Niedermendig tuff ribs.
