Wäinö Aaltonen Museum of Art or WAM for short, is an art museum in central Turku, Finland dedicated especially to modern art. The museum is located on the east bank of the Aura River. The permanent exhibition is based on the art collection of City of Turku, which includes a large collection of works by Finnish artist and sculptor Wäinö Aaltonen. Temporary exhibitions focus on Finnish and international modern art.
In March 1964, the City Council of Turku approved the proposal to establish a museum dedicated to Wäinö Aaltonen, and Aaltonen himself signed an agreement donating a basic collection to the proposed museum. Construction started in October 1965. The drawings for the modernist building was made by Wäinö Aaltonen's son Matti Aaltonen and his wife Irma Aaltonen, but Wäinö Aaltonen himself also played an active part in the planning. The Museum was officially opened on 17 September 1967.
The exhibition rooms of WAM have been designed to fully meet modern requirements. The architecture of the rooms is clean and well lit; natural light is generously provided through wide windows and numerous skylights. Inside the museum there is also a cafeteria and a shop.
