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.
Old Trinity Cathedral
The Old Trinity Cathedral (also known as Peter's Trinity Cathedral, Троице-Петровский собор) was the oldest church in St. Petersburg, Russia. It was there that Peter the Great celebrated the end of the Great Northern War in 1721 and was proclaimed the first Emperor of All Russia. It was one of the city's most cherished monuments until the Soviets ordered its destruction in 1933. The site on the Neva River bank is commemorated by a chapel.
