The princessehof in Leeuwarden was built as a city mansion in 1693 for the Aylva family. The house was sold to Marie-Louise of Hessen-Kassel in 1713. Marie-Louise is the mother of Stadholder Willem IV and widow of Johan-Willem-Friso, stadholder of Frisia, Groningen and Drenthe.
Marie-Louise collected a lot of ceramics and at the moment the museum has a big collection of those. Here the website of the museum: Keramiekmuseum Princessehof
