Home to the Slovenian Philharmonic founded in 1701, this small but very atmospheric venue in the southeast corner of Kongresni trg also stages concerts and hosts performances of the Slovenian Chamber Choir (Slovenski Komorni Zbor) founded in 1991. Haydn, Beethoven and Brahms were honorary Philharmonic members, and Gustav Mahler was resident conductor for a season (1881–82).
