History+
The origins of Egmond Castle are closely linked to Egmond Abbey. In 1129, a steward named Berwout was appointed, whose descendants received hereditary lordship over Egmond. The first fortified estate, built around 1050 or 1150, was burned down in 1205 during the Loon War of Succession. As a replacement, a round stone water castle was built starting in 1206, first documented in 1228. Around 1300, this castle lost its significance and was replaced by a new complex on the former outer bailey. This third castle was expanded in two phases in the 14th century and supplemented by a gatehouse around 1500. John III of Egmond, the first Count of Egmond, had the castle enlarged and decorated in the 15th century. In 1573, Egmond Castle was set on fire by troops of Diederik Sonoy on the orders of the Prince of Orange to prevent its use by Spanish troops.
