The Gösta Serlachius Fine Arts Foundation maintains two museums. The roots of the museums stretch back to the history of Serlachius family that is well-known for its role in Finnish paper industry as well as art collecting, but also to the history of a Finnish forest industry and to the history of a small mill town of Mänttä.
The art museum Gösta showcases annually several changing exhibitions of contemporary art as well as the pearls of the Gösta Serlachius Fine Arts Foundation's collection. The collection is one of the largest private art collections in Scandinavia.
Art museum Gösta's exhibitions cover two buildings: the former private residence of Gösta Serlachius, Joenniemi manor and the internationally renowned pavilion, an example of modern wood construction that was opened 2014.
Gustaf Museum tells stories. In the former head office of the historical forest combine G.A. Serlachius Ltd. curious and surprising exhibitions are intermingled with the colourful history and magnificent architecture of the building.
