Լուիզա թագուհու թատրոնի շենք, Historical theater building in Sovetsk, Russia.

The Queen Louise Theater is a tall four-storey building on the pedestrian Pobedy Street in Sovetsk. Its facade is ornate in the Baroque manner, and after the fires of 2015 and 2019 the roof and interior are destroyed, leaving a ruin behind the decorated front.

Built in Tilsit in 1910, the building was the smallest and cheapest cinema in the city, nicknamed the "flea cinema" by locals and popular with young audiences. It closed in 1944 and survived the war intact, then housed the Kaliningrad Regional College of Culture and Arts until that school closed in 2010. Fires in 2015 and 2019 destroyed the roof and interior; a restoration contract worth 396.9 million rubles was signed in 2024.

Locals nicknamed the cinema "flea cinema" because it was the smallest and cheapest venue in Tilsit, and young people bought tickets for the first three or four rows, paid for out of pocket money. After the war the building housed the Kaliningrad Regional College of Culture and Arts until it closed in 2010.

The building stands on the pedestrian Pobedy Street in central Sovetsk. It is a ruin: the roof burned in 2015, a second fire in June 2019 destroyed about 600 square metres, and one pediment collapsed after a storm in 2013. View it from the street only; entry is unsafe. A Moscow contractor signed a restoration contract in 2024.

The building was listed as a cultural heritage site by order No. 3 of the Kaliningrad Region's state protection service on 18 January 2010. A 2024 contract with a Moscow contractor, worth 396.9 million rubles, covers restoration, after which a museum and exhibition complex is planned here.
