Philharmonic Hall, Concert hall in Congress Square, Slovenia

The Philharmonic Hall is a concert venue in Congress Square, Ljubljana, featuring a neo-Renaissance facade with rounded corners and symmetrical design created by architect Adolf Wagner in 1891. The building occupies a historic site and was later enlarged with an extension designed by the renowned architect Jože Plečnik.

The Philharmonic Society commissioned architect Adolf Wagner to design the building; his 1888 plans were built between 1889 and 1891 under builder Vilijem Treo, who adapted them slightly, and work finished a few years after the 1895 Ljubljana earthquake. It replaced the Stanovsko Theatre, destroyed by fire in 1885. In 1937 Jože Plečnik added a colonnade wing on the river side and the main hall gained a balcony; the colonnade was glazed in the 2001 renovation.

The two halls were renamed on 13 January 2008, the centenary of the Slovenian Philharmonic: the Great Hall became Dvorana Marjana Kozine and the Small Hall Dvorana Slavka Osterca. A bust of Marjan Kozina by sculptor Janez Pirnat was placed in the entrance hall that day. In the Osterc Hall hang Saša Šantel's 1936 painting of Slovenian composers and Zmago Modic's 2005 picture of the orchestra.

The venue is located at Congress Square in central Ljubljana and is easily accessible on foot with clear directions to the box office and entrance areas. Box office hours are limited, so it is wise to check ahead and allow time to arrive before performances.
