Section of the fortress rampart connecting the Tsar’s and Menshikov bastions. Named after the Peter Gate built within it.

Constructed in stone between 1717 and 1719 according to the design of architect and fortification engineer D. Trezzini, replacing the previous wooden-earth fortification. Under the curtain near the Menshikov bastion ran a fortress canal, which was filled in 1882. Originally, the curtain had twenty two-tiered casemates. Between 1907 and 1909, they were rebuilt into single-tier casemates with altered window openings.

On Trinity Square in front of the fortress, the city’s first buildings were constructed. They housed government institutions, a printing house, a shopping arcade, and customs offices. The first port of Petersburg was also located here. Petersburg arose as a fortress city, serving as both a military and commercial port. From this square, residents in the city’s early years could enter the territory of the Peter and Paul Fortress through the Peter Gate. The casemates were adapted for the barracks of the Invalid, Artillery, and Engineering companies of the fortress garrison, officers’ apartments, and warehouses for food supplies and construction materials. To the right of the gate was the guardroom — the cordegard, with two casemates for general prisoner detention. At the end of 1825 and beginning of 1826, sailors of the Guards Crew who participated in the Decembrist uprising were held here.
