Transfiguration Cathedral (official name: Russian: собор Преображения Господня всей гвардии, The Cathedral of the Lord's Transfiguration of all the Guards) is an Eastern Orthodox cathedral belonging to the Diocese of St. Petersburg. It is located on Transfiguration Square (Russian: Преображенская площадь), just off Liteyny Prospekt near the Chernyshevskaya metro station. Unlike most Russian places of worship, this archictural monument has never ceased operating as a place of worship.
