In the first years after World War II renovators restored the historical ground-floor arcades and pillars that supported the first-floor platform, cleared up vaulted and caissoned ceilings in the galleries, and removed "unhistoric" 19th-century oil paint murals inside the churches.[9] Another round of repairs, led by Nikolay Sobolev in 1954–55, restored original paint imitating brickwork, and allowed restorators to actually dig inside old masonry, revealing the wooden frame inside it.[9] In the 1960s, the tin roofing of the domes was replaced with copper.[14]
The last round of renovation was completed in September 2008 with the opening of the restored sanctuary of St. Alexander Svirsky.[94] The building is still partly in use today as a museum but is occasionally used for periodic services by the Russian Orthodox Church since 1991.
