History of Saint Petersburg
Founded by Tsar Peter the Great on 27 May 1703. It became capital of the Russian Empire for more than two hundred years (1712–1728, 1732–1918). St. Petersburg ceased being the capital in 1918 after the Russian Revolution of 1917.
Pavlovsk, Saint Petersburg
The town developed around the Pavlovsk Palace, a major residence of the Russian imperial family. Between 1918 and 1944, its official name was Slutsk, after the revolutionary Vera Slutskaya, and then was changed back to Pavlovsk. Pavlovsk is part of the UNESCO World Heritage Site "Saint Petersburg and Related Groups of Monuments".
