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.
St. Petersburg, Florida
A local legend says that John C. Williams and Peter Demens flipped a coin to see who would have the honor of naming the city. When Demens won the coin toss the city was named after Saint Petersburg, Russia, where Peter Demens had spent half of his youth, while John C. Williams named the first hotel after his birthplace, Detroit (a hotel built by Demens). The Detroit Hotel still exists downtown, but has been turned into a condominium. The oldest running hotels are the historic Pier Hotel, built in 1921, formally Hotel Cordova and The Heritage Hotel (now named Hotel Indigo), built in 1926.
