Samson defeats the lion, memorializing symbolically the victory of Russia over Sweden. Peter started the war with Sweden with no apparent provocation. But when it was over twenty-one years later, Russia had built a naval fleet and had captured and held territory lost to Sweden in 1613, giving it a desperately needed Baltic port. All that was needed was a port city to go with it. After an early victory at the mouth of the Neva River in 1703, Peter began building one of the great cities of Europe to go with it, St. Petersburg, named after his favorite patron saint.
