The exhibition “Museum of Savva Yamshchikov’s Friends” was opened in the City Exhibition Hall of Petrozavodsk. Among the organizers is the State Museum-Monument “St. Isaac’s Cathedral,” and this is no coincidence. “Savva of All Rus’,” as Saveliy Yamshchikov’s friends called him, made a great contribution to the development of restoration and artistic art in both Karelia and St. Petersburg.
