Built in stone in 1708–1709 according to the design of architect and fortification engineer D. Trezzini, replacing a wooden-earth fortification. Originally, the curtain wall had twenty-one two-tier casemates. At the end of the 19th and beginning of the 20th centuries, they were rebuilt into single-tier casemates with altered window openings.
Under the arch of the Kronverk Gate was the entrance to the guardroom — the cordegardia. The Invalid and Artillery companies of the fortress garrison, as well as the Complete and Consolidated infantry battalions, were quartered in the curtain wall. In 1826, while awaiting execution, the leaders of the Decembrist movement P. I. Pestel, K. F. Ryleev, S. I. Muravyov-Apostol, M. P. Bestuzhev-Ryumin, and P. G. Kakhovsky were held here.
Currently, it is under the jurisdiction of the State Museum of the History of St. Petersburg and the state enterprise "St. Petersburg Mint."
