Tartu Art Museum is an open and welcoming museum, full of exciting encounters with new and old art from the 20th and 21st centuries. Also called Tartmus, the space builds bridges between the past and the present and speaks to contemporary people on important topics. The museum was founded in 1940 to collect, preserve, and promote contemporary art. Tartmus is located in a crooked house in Tartu Town Hall Square, which was built in 1793. The house has been slanted by 5.8 degrees due to the marshy banks of the  Emajõgi River. This means that the house is more tilted than the Pisa Tower. The art collections and the professional library are located at Rüütli 23.
