A former medieval monastery that served as the residence of William of Orange during the Dutch Revolt, and the place where he was assassinated in 1584. The building is now Delft's main museum, combining the story of William's life and death with exhibitions on Delft's Golden Age — Vermeer, Delftware pottery, and the city's role in the Dutch East India Company.
The assassination spot in the stairwell, with the original bullet marks preserved in the plaster, is the most visited point in the museum. But the rest of the collection is strong: the courtyard is peaceful, the Golden Age paintings are excellent, and the Delftware collection provides context for the blue-and-white pottery you see in every shop in town. On Sint Agathaplein, a few minutes' walk from the Markt.
