This church has never ceased operating as a place of worship
An architectural monument construction by order of Empress Elizaveta Petrovna (architect M. G. Zemtsov) on the site of the quarters for the Preobrazhensky Life Guard Regiment to commemorate the Empress' accession to the throne, which was assisted by soldiers and officers of the regiment. The construction work, which lasted from1743 to 1754, was supervised by architect P. A. Trezzini, who built a five-dome Baroque cathedral. The five-tier iconostasis and the altar ciborium were made by Moscow engravers Kobylinsky according to the sketches of architect F. B. Rastrelli. The icons were painted by M. L. Kolokolnikov. In 1796, the church acquired the status of the Cathedral of All Guards, but in 1825 was severely burnt. In 1825-29, the Cathedral was restored by architect V. P. Stasov, who redesigned the cathedral in the Empire style. The facade of the main building is decorated with a four-columned portico of the Ionic order and stucco moulding reliefs. The building has an impressive illuminated dome drum crowned with a cupola, with four belfry domes on the corners. The four-tier iconostasis was made according to the drawings of Stasov, the icons were created by artists G. I. Ugryumov, A. I. Ivanov, V. K. Shebuev, A. E. Egorov and others; interior paintings were made by artists F. P. Brullo, F. I. Brandukov and S. A. Bessonov according to the sketches by Shebuev. In 1832-33, a fence made of captured Turkish cannons (a monument to the victory in the Russian-Turkish War of 1828-29) was constructed around the cathedral to the designs of Stasov. In 1886, a chapel was built within the precinct (architect I. B. Slupsky). In 1916 construction started on the burial vault for officers killed during World War I (architect S. O. Ovsyannikov; never completed). The Holy Transfiguration Cathedral treasured regimental relics and trophies, its walls bore bronze plaques with the names of Preobrazhensky Regiment officers, fallen in battle. From 1871, the cathedral oversaw a parish charitable society, supporting a hospice, an orphanage, a canteen, a school for soldiers' children and free apartments, and from 1912 - the Brotherhood of Sobriety and Virtue. On the holiday of Transfiguration of Our Saviour Jesus Christ a traditional fruit market was arranged by the cathedral. After October 1917, the Holy Transfiguration Cathedral remained an operational church. The Holy Transfiguration Cathedral gave its name to Preobrazhenskaya Square.
