Drakensteyn is a small castle constructed in the years 1640–1643 for a Gerard van Reede Läm. A house called Drakesteijn at this location was first mentioned in 1359. It is owned by Princess Beatrix of the Netherlands, the country's former Queen who abdicated in 2013. Beatrix bought the castle in 1959, when she was the heir to the Dutch throne, and took up residence in 1963. After her marriage in 1966 she continued to live there with her husband, Prince Claus and later their three sons as well. After Beatrix succeeded her mother Juliana as Queen of the Netherlands in 1980, the family moved to The Hague in 1981. The royal connection aside, its most distinctive feature is its octagonal shape. It is surrounded by a moat that can be crossed via a bridge. Its style can be described as Classicist.

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.
