Architect Daniël Marot designed the Kneuterdijk palace in The Hague, The Netherlands, for Johan Hendrik, Count Van Wassenaer van Opdam. It was built between 1720 and 1730. Later, in 1816, the palace was bought by King Willem I of the Netherlands for his son, the later King William II who was married to Anna Pavlovna, a daughter of the Russian Czar Paul I. After WW II it was the seat of the Dutch War Tribunal. After extensive renovations it is the seat of the Dutch Council of State, the highest advisory body to Dutch Government.
