A magnificent mansion built in 1685, now open to the public. It's rooms are stuffed with treasures from the collection of its last owners, Sandrina Holthuysen and Abraham Willet who died childless in the 19th century and left the house to the state. My favourites are the dining room, set for a magnificent banquet, and the kitchen where the work was done.
