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 building were made by Irma and Matti Aaltonen, but Wäinö Aaltonen himself also played an active part in the planning. The Wäinö Aaltonen Museum of Art was officially opened on 17 September 1967.
The Wäinö Aaltonen Museum of Art is located on the east bank of the Aura River. The permanent exhibition is based on the art collection of the 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.
