Petrine Baroque (Rus. Петровское барокко) is a name applied by art historians to a style of Baroque architecture and decoration favoured by Peter the Great and employed to design buildings in the newly founded Russian capital, Saint Petersburg, under this monarch and his immediate successors.
Different from contemporary Naryshkin Baroque, favoured in Moscow, the Petrine Baroque represented a drastic rupture with Byzantine traditions that had dominated Russian architecture for almost a millennium. Its chief practitioners - Domenico Trezzini, Andreas Schlüter, and Mikhail Zemtsov - drew inspiration from a rather modest Dutch, Danish, and Swedish architecture of the time.
Extant examples of the style in St Petersburg are the Peter and Paul Cathedral (Trezzini), the Twelve Colleges (Trezzini), the Kunstkamera (Zemtsov), Kikin Hall (Schlüter) and Menshikov Palace (Giovanni Fontana)
