Brüggen Castle, Water castle in North Rhine-Westphalia, Germany.

Brüggen Castle is a brick water castle in Brüggen, North Rhine-Westphalia. Its medieval core had a nearly square 40 × 37 m plan with four round corner towers, surrounded by a 14 m wide moat and a 1.60 m thick ring wall. The three-storey palas and its round southwest tower survive, the latter topped in 1994 with a conical roof modelled on 17th-century examples.

The Counts of Kessel built the castle between 1264 and 1284 to guard a ford over the Schwalm; it was first documented in 1289. In 1306 it passed to the Dukes of Jülich, who around the mid-14th century replaced the old buildings with a brick quadrangular castle. In 1473 Burgundian troops stormed and burned it, after which it was rebuilt with a third storey and, from 1520, new bastions.

The castle houses a hunting and natural history museum where visitors can explore exhibits on local wildlife and the region's past. The collection shows how closely people in this area once lived alongside the surrounding nature.

The castle is in the center of Brüggen and easy to reach on foot. Allow enough time to visit both the outside of the building and the museum inside.

The castle's southwest tower has a top storey of Maastricht limestone, unlike the brick floors below it. Its conical roof was only replaced in autumn 1994, modelled on 17th-century examples. The tower once held a dungeon and could be entered only through a high entrance on the first floor.
