Saint George Cathedral in Gus-Khrustalny, Eastern Orthodox cathedral in Gus-Khrustalny, Russia.

Saint George Cathedral is a former Orthodox church built in 1892–1903 to a design by architect Leonty Benois, unusual among Russian Revival churches for its basilica plan with a raised central nave. Its dome, bell tower and upper parts were demolished in the Soviet period. Since 1983 the building has housed the Crystal Museum of the Vladimir-Suzdal Museum-Reserve.

Construction began in 1892, financed by glass manufacturer Yu.S. Nechaev-Maltsov, and was completed in 1903 under architect L.N. Benois. The project emerged during the peak of local glass production and reflects the economic power of that era.

The cathedral was consecrated in 1904 to Saint George the Victorious and decorated to a design by Viktor Vasnetsov. Its former religious art now shares the building with the Crystal Museum, opened here in 1983 as part of the Vladimir-Suzdal Museum-Reserve. In 2019 a Divine Liturgy was again celebrated in the former church.

The main entrance is at Kalinina Street 2a in the center of the city, where visitors can also access the attached crystal museum. It is best to check opening hours beforehand and allow time to explore both the cathedral and the museum during your visit.

The Last Judgment fresco by Viktor Vasnetsov survives only in part, as does the mosaic "O Thee Rejoiceth, O Gracious One", made by the St Petersburg mosaicist Vladimir Frolov. The Soviet-era demolition of the dome, bell tower and upper part of the building cut the decoration short; what remains is the fragment visitors see today.
