The Cathedral of the Holy Image of the Savior in the Winter Palace is the house church of the Russian imperial family, located in the Winter Palace in St. Petersburg, the main residence of the Russian emperors. The church is one of the few buildings in which, after the fire of 1837, the architect V.P. Stasov recreated the original Rococo interiors in 1839, designed by Francesco Bartolomeo Rastrelli, the creator of the fourth Winter Palace.
The restoration project for the Great Church, however, was developed by ACM architects in the early 21st century.
