The Lithuanian National Philharmonic Society is Lithuania's principal state concert organization, headquartered in Vilnius Old Town. Operating under the Ministry of Culture, its mandate is to foster, preserve, and disseminate national and international classical and contemporary music by organizing concert seasons, staging prominent festivals, and managing resident ensembles such as the Lithuanian National Symphony Orchestra. Founded on December 4, 1940, the society is housed in a historic building that hosted the Great Seimas of Vilnius in 1905 and was officially designated a national cultural institution in 1998.
