Burg Wassenberg, Medieval castle in Wassenberg, Germany.

Burg Wassenberg is one of only three hill castles on the Lower Rhine, alongside Kleve and Liedberg. Its surviving parts, almost all from 1420, stand within the town walls on a hill falling away on all sides. The four-storey square brick keep from the first half of the 15th century serves today as an observation tower with a view over the Rur valley. On the south-west side is the gate tower with a basket-arched passage and a Gothic pointed arch on its inner side; its upper storey and roof cap date from the 18th century.

In 1020 Emperor Henry II granted Wassenberg castle and land to Gerardus von Antoing, who took the title Count of Wassenberg and founded the comital house that, after four generations, established the County of Guelders. The castle itself is older, its predecessor probably a Roman fortification. In 1131 Jutta von Wassenberg married Walram of Limburg, bringing Wassenberg to Limburg; in 1202 a son of the Duke of Limburg inherited it and could style himself only Lord of Wassenberg.

Since 15 November 2018 the castle has housed the restaurant "Burg Wassenberg by Savio"; the hotel reopened in May 2019 after partial renovation. The name Wassenberg is tied to the counts who took their title from the castle, and the town's charter of 1273 was confirmed in the 1972 municipal reform.

The site is best explored on foot, with sturdy shoes recommended due to the elevated location and potentially uneven ground. The hotel offers parking and electric charging stations for visitors arriving by car.
