Just a few blocks south of the Dom, this former convent houses a vast collection of religious history and sacred art. There are magnificent altarpieces, ecclesiastical vestments, beautifully illustrated manuscripts, sculptures, and paintings—including works by Rembrandt and Frans Hals. Note the painting of a silvery-bearded God, by Pieter de Grebber (1640), holding what appears to be a crystal ball, inviting Jesus to sit at his right hand, in a cherub-bedecked chair.
Temporary exhibitions here are first-rate. Cross the first-story walkway to get a great view of the cloister gardens.
