The Slovenj Gradec Art Gallery () was founded in 1957 and is located on the first floor of the old town hall in the town centre. The gallery hosted international fine art exhibitions under the sponsorship of the United Nations in 1966, 1975, 1979, 1985, and 1991. The 1997 exhibition "The Artist and Urban Environment" displayed art activity in Peace Messenger Cities from all over the world. In 2012, Slovenj Gradec and Ptuj were partners with Maribor, the European Capital of Culture. As a result, the gallery presented further exhibitions that attracted Europe-wide attention.
