The Huys Dever is a small castle probably built shortly after 1375 by Reinier Dever or d'Ever, a member of an old noble family from Holland. The castle was a typical stronghold that was at one time situated on the edge of a lake called the Lisser Poel (since poldered in) that itself was in connection to the Haarlemmermeer (itself a polder since in 1853). In 1630 a stately home was built on to the tower and became a summer residence, but after the Haarlem Lake was poldered in the 19th century it fell into disuse and became a ruin. In 1973 restoration began and the roof was built in the manner of 16th century carpentry.
The building houses a small archeological museum with finds dug up in the former moat around the building. It has been voted a very important rijksmonument for its early medieval remains. The building is open to visitors.

Le Lude is the most northerly château of the Loire Valley and one of the last important historic castles in France, still inhabited by the same family for the last 260 years. The château is testimony to four centuries of French architecture, as a stronghold transformed into an elegant house during the Renaissance and the 18th century. The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
