Bánffy Castle is a baroque building of the 18th century in Cluj-Napoca, designed by the German architect Johann Eberhard Blaumann. Built between 1774 and 1775 it is considered the most representative for the baroque style of Transylvania. The first owner of the palace was György Bánffy 1746–1822), the governor of Transylvania.
Francis II, Holy Roman Emperor and his wife Caroline Augusta of Bavaria were hosted in the palace during their visit in Kolozsvár, between 18 and 27 August 1817. This was the first occasion when a ruler from the Habsburg family visited the city. Franz Joseph I of Austria was also the guest of the palace betweem 2-4. August 1852 and 22-24 September 1887.
In February 1951 the council of the city decided to empty the palace to establish an Art Museum there; the works were finished in the summer of 1954. The museum was opened in the restored palace on 30. December 1965. The cinema occupying the inner yard of the palace was demolished in 1974.
