Opera house in Bytom, Neoclassical opera house in Władysława Sikorskiego Square, Bytom, Poland.

The Gmach Opery Śląskiej w Bytomiu is a neoclassical theatre building erected between 1898 and 1901 on a corner plot of 5,090 m². Its two-part plan places the main opera stage, originally seating 631 and now 391, in the eastern wing, while the western wing holds the Adam Didur concert hall, reduced from 520 to 200 seats. Two representational facades lead inside; the western one has a central risalit topped by a tympanum.

Architect Alexander Böhm designed this building, which opened in 1901 as a major cultural venue in Silesia. The structure gained monument status in 1977, recognizing its role in the region's cultural landscape.

The foyer holds a memorial plaque to Franz Landsberger, the banker and music lover who founded the Konzerthausgesellschaft to build the theatre; the Nazis removed it in the 1930s. Inside, another plaque honours Napoleon Siess, director of the Silesian Opera. Since 1957 a bust of Chopin by Aleksander Żurakowski has stood before the western facade.

The opera house presents performances throughout the year, ranging from operas and ballets to concerts and theatrical productions. It sits in the city center and is easily accessible for visitors looking to catch an evening performance.

A memorial plaque to Franz Landsberger, the banker who initiated the theatre's construction, was placed in the foyer in 1925 and removed by the Nazis in the 1930s. Inside, another plaque honours Napoleon Siess, director of the Silesian Opera. The 2000 fire destroyed the roof and the former concert hall, which was later rebuilt as a concert hall while a new ballet hall with a modern dome was added on the top floor of the west wing.
