In 1709, Peter the Great moved the ship docks from Voronezh to the new location and started the construction of a new fortress, which at different times was called Sereda, Osered, and Oseredskaya. In 1711, a garrison was moved here from the St. Paul Fortress on the Sea of Azov, and the fortress was renamed Pavlovskaya (sometimes called Novopavlovskaya), and the town around it—Pavlovsk. By the end of the 18th century the town lost its importance and went into decline.
