Haamstede Castle (Dutch: Slot Haamstede) is an old castle in the village of Haamstede on the island of Schouwen-Duiveland. It is a rijksmonument. The keep dates from the 13th century. In 1525 Haamstede castle (except the donjon) was destroyed by fire. The castle's current appearance is largely due to the poet and captain Jacob van den Eynde, who acquired the castle and rebuilt it after the devastating fire. In 1973 the castle has been restored, and in 1981 sold to Natuurmonumenten Society. However, the family preserved the right to live in the castle.
