Petrine Baroque (Russian: Петровское барокко) is a style of 17th and 18th century 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 dramatic departure from 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.
