Peter the Great
While the Poles fought the Swedes, Peter founded the city of Saint Petersburg in 1703, in Ingermanland (a province of the Swedish Empire that he had captured). It was named after his patron saint Saint Peter. He forbade the building of stone edifices outside Saint Petersburg, which he intended to become Russia's capital, so that all stonemasons could participate in the construction of the new city. Between 1713 and 1728 and in 1732–1918, Saint Petersburg was the capital of imperial Russia.
Coat of arms of Saint Petersburg
The historical coat of arms of St. Petersburg was approved in 1730, confirmed in 1780, and amended in 1857. It had never been declined and was brought back into use in 1991. The coats of arms of the Holy See and Vatican City (the original "city of St. Peter") served as the prototype for the coat of arms of St. Petersburg.
