Ljubljana Cathedral (), or St. Nicholas's Cathedral (), serves the Archdiocese of Ljubljana. Easily identifiable due to its green dome and twin towers, it is located at Cyril and Methodius Square (, named for Saints Cyril and Methodius) by the nearby Ljubljana Central Market and Town Hall. The Diocese of Ljubljana was set up in 1461. Between 1701 and 1706, the Jesuit architect Andrea Pozzo designed the Baroque church with two side chapels shaped in the form of a Latin cross. The dome was built in the centre in 1841. The interior is decorated with Baroque frescos painted by Giulio Quaglio between 1703–1706 and 1721–1723.
