The Grand Church of the Winter Palace (Russian: Cобор Спаса Нерукотворного Образа в Зимнем дворце) in Saint Petersburg, sometimes referred to as the Winter Palace's cathedral, was consecrated in 1763. It is located on the piano nobile in the eastern wing of the Winter Palace, and is the larger, and principal, of two churches within the Palace. A smaller, more private church was constructed in 1768, near the private apartment in the northwest part of the wing. The Grand Church was designed by Francesco Rastrelli, and has been described as "one of the most splendid rooms" in the Palace. Today, the church is an unconsecrated exhibition hall of the State Hermitage Museum.
Construction of the church began on 14 October 1753 (Julian calendar). Six years later, the interior design was executed by the Italian artists Carlo Zucci, Francesco Martini, Giovanni Antonio Veneroni and the sculptor G. B. Gianni. Rastrelli was personally in charge of the three-tier iconostasis where the icons were painted by Ivan Ivanovich Belsky and Ivan Vishnyakov. The Italian Francesco Fontebasso painted the evangelists in the church's spandrels and the "Resurrection of Christ" plafond in the vestibule.
The Grand Church was one of the final parts of the palace to be completed. When the Palace was first inhabited on 6 April 1762, the cathedral was not yet completed, so a temporary church of the Resurrection of Christ was consecrated by Archbishop Dimitry Sechenov of Novgorod.
