Kasteel Duurstede (Duurstede Castle) is dating back to the 13th century and is one of the oldest medieval castles in the Netherlands. Around 1270 Zweder I van Zuylen van Abcoude built a freestanding keep on a raised and moated site nearby the (lost) city Dorestad. This building was about 11 meters high and had 2.5 meter thick walls. Later on an extra floor and a residential wing with a great hall were added.

Until the beginning of the 15th century the castle was possessed by the Van Zuylen van Abcoude family, when they were forced to sell it to the bishops of Utrecht who kept it until 1580. After that year Kasteel Duurstede fell to the States of Utrecht. They had no money to maintain the castle, so it slowly fell into decay. And after the French troops had devastated the town of Wijk bij Duurstede in 1672 the locals repaired their houses and the town walls with stones from the castle.

In 1852 the town council became owner of the castle and turned the fortifications around the castle into a park. Until around 1925 the castle could only be reached with a little ferry; nowadays there is a little drawbridge.

Today only the two towers and some of the walls remain, but the castle has been renovated to include a terrace cafe, gazebo in the garden and rooms inside which are used for events or weddings.
