Several important buildings face the square. Among them, there is the early Baroque Ursuline Church of the Holy Trinity, the Casino Building, one of the few Neoclassical buildings remaining in Ljubljana after the earthquake of 1895, the Slovenian Philharmonic building, and the rectorate of the University of Ljubljana, formerly the seat of the Provincial Diet of the Duchy of Carniola. The "Slovenska matica" publishing house also has its seat on the square.
