Considered a key symbol of Kaliningrad's cultural life, the organ hall of the Kaliningrad Regional Philharmonic Hall is housed in the building of the former Catholic Church of the Holy Family. The church was built in the early 20th century in the neo-Gothic style by architect Friedrich Heitmann, one of the best known practitioners in East Prussia. Many of his works are now sightseeing sites in Kaliningrad.
The Philharmonic Hall opened in the restored church building in 1980. Two years later, an organ of the Czech company Rieger-Kloss, was installed in the hall to be Kaliningrad's first such instrument. Thanks to special building techniques, the Philharmonic Hall boasts fine acoustics and a church atmosphere untypical of a concert hall. It is a venue for numerous art festivals, such as the Amber Necklace, Bakhosluzheniye, Russian Music in the Baltic.
