Cankar Hall (Slovene: Cankarjev dom) is a cultural and congress center in Ljubljana, Slovenia. It stands on the central Republic Square (Trg republike), opposite the Parliament of Slovenia.
It is named after the writer Ivan Cankar. The building was designed by the architect Edvard Ravnikar and was built between 1977 and 1982. Construction was funded entirely by the Socialist Republic of Slovenia. The center has four halls named after Slovene artists: Gallus Hall (named after the Baroque composer Jacobus Gallus), Linhart Hall (named after Enlightenment erudite and playwright Anton Tomaž Linhart), Kosovel Hall (named after the modernist poet Srečko Kosovel), and Štih Hall (named after literary critic Bojan Štih).
Cankar Hall has a large foyer in which events are held (artistic performances, dances, book fairs, etc.). In front of the building stands a monument to Ivan Cankar, designed in 1982 by the sculptor Slavko Tihec.
The ground floor of Cankar Hall, like most of Republic Square, was owned by the Roman Catholic Church until 1960, when it was nationalized by the state. During the building of Cankar Hall, remnants of the ancient Roman town of Emona were found. Most of the finds have been transferred to the National Museum of Slovenia, which stands on the opposite side of the square.
