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.References:
The Château Comtal (Count’s Castle) is a medieval castle within the Cité of Carcassonne, the largest city in Europe with its city walls still intact. The Château Comtal has a strong claim to be called a 'Cathar Castle'. When the Catholic Crusader army arrived in 1209 they first attacked Raymond-Roger Trencavel's castrum at Bèziers and then moved on to his main stronghold at Carcassonne.
The castle with rectangular shape is separated from the city by a deep ditch and defended by two barbicans. There are six towers curtain walls.
The castle was restored in 1853 by the architect Eugène Viollet-le-Duc. It was added to the UNESCO list of World Heritage Sites in 1997.
