The Frans Hals Museum is a hofje and municipal museum in Haarlem, Netherlands. The museum was founded in 1862 in the newly renovated former cloister located in the back of the Haarlem city hall known as the Prinsenhof. The collection is based on the wealthy collection of the city hall itself, including more than a dozen paintings by Frans Hals, for whom it is named, but also contains other interesting Haarlem art from the 15th century up to the present day. The collection moved to the present location in 1913, and the modern collection is located in the two buildings on the town square called the Hallen, for the former occupations of the buildings, the Fish Hall and the Meat Hall. The main collection, including the Frans Hals paintings, is currently located on the Klein Heiligland, across the street from the Haarlem historical museum.
