Initially a convent, these late-Gothic buildings (15C-16C) became the residence of William, Prince of Orange in 1572; he was assassinated here in 1584. In the 17C, the palace became a cloth market. It houses a museum, whose collections focus on the Eighty Years War (1568-1648) and on the House of Orange-Nassau. Still-lifes, collective portraits of civil guards and lovely tapestries are also showcased.
