The Art Museum of Estonia was founded on November 17, 1919, but it was not until 1921 that it got its first permanent building — the Kadriorg Palace, built in the 18th century. In 1929 the palace was expropriated from the Art Museum in order to rebuild it as the residence of the head of state of Estonia.
The Art Museum of Estonia was housed in several different temporary spaces until it moved back to the palace in 1946. When Estonia regained independence in 1991, the Kadriorg Palace was closed for renovation, since it had fallen into almost complete disrepair during the Soviet occupation of Estonia (1944–1991). At the end of 1991, the parliament of the country decided to secure the construction of a new building for the Art Museum of Estonia in the Kadriorg park. Until the new building was finished, the Estonian Knighthood House at Toompea Hill in the old town of Tallinn served as the temporary main building of the Art Museum of Estonia. The exhibition there was opened on April 1, 1993. The Art Museum of Estonia permanently closed down the exhibitions in that building in October 2005. In the summer of 2000 the restored Kadriorg Palace was opened, but not as the main building of the Art Museum of Estonia, but as a branch. The Kadriorg Art Museum now exhibits the foreign art collection of the Art Museum of Estonia.
Kumu includes exhibition halls, an auditorium that offers diverse possibilities, and an education centre for children and art lovers (see above). Kumu has a thorough collection of Estonian art, including paintings by Carl Timoleon von Neff, Oscar Hoffmann, Ants Laikmaa, Julia Hagen-Schwarz, Oskar Kallis, Konrad Mägi, Jaan Koort, Henn Roode, and Johannes Greenberg.
The museum served as one of several locations for the fictional Oslo Freeport for the 2020 movie Tenet.[4]
