In 1741, Kvasov helped
Mikhail Zemtsov to prepare
coronation celebrations in
Moscow. Two years later, he was entrusted with interior decoration of the
Catherine Palace, which resulted in the
Grand Ball Hall and other celebrated rooms. The
Saviour Church on Hay Square,
Znamenka Palace, and the palace of
Aleksey Bestuzhev are also attributed to Kvasov.
Aleksey Razumovsky was Kvasov's long-time employer. In 1748 he went to the court of the Ukrainian
hetman Kirill Razumovsky, Aleksey's brother, to design the residences and churches in
Baturin,
Glukhov, and
Koselets. In 1770, he was made Principal Architect of
Little Russia. The cathedral in Kozelets is his major surviving work in the
Ukrainian Baroque idiom. Kvasov's younger brother
Aleksei is credited with devising the general layout of
Kazan (1766),
Tver (1767),
Astrakhan (1768),
Kharkov (1768), and the Admiralty part of
St Petersburg. == References ==
