The fortress was founded by Peter the Great in 1703 on Zayachy island, which is located on the Neva River. It was built as a war fortress as at that time Russia was involved in the Great Northern war against Sweden for the going to the Baltic Sea. The first fort was constructed with six wooden bastions. Later it was rebuilt with stone.

In 1720 the fort was used as a base for the city garrison and also as a prison for noble and political prisoners. The main Peter and Paul Cathedral of the fortress was built in 1712-1733.
Russian tsars from Peter the Great to Nicholas II (except for Peter II and Ivan IV) are buried in the Peter and Paul Cathedral Cathedral.
