Yakor'naya Square, 3, Saint Petersburg, Russia, 197762
The dock basin was built near the Naval St. Nicholas Cathedral, next to the Summer Garden, according to the design of engineer Lyuberas. Its construction lasted from 1734 to 1752. The average water level in the basin was 11.4 meters.
Right next to the basin, a pumping station was installed. Water was pumped from the basin by a pump into a drainage channel, and then flowed into the Obvodny Canal, from which it was discharged into the Gulf of Finland.
The walls of the basin are laid out of stones, shaped like honeycombs. From the basin, there is a wonderful view of the Naval Cathedral.
A very surprising and interesting fact: despite the grandeur and significance of such a structure, today there are no precise practical data on how the dock construction proceeded in the 18th century. Neither drawings nor diagrams reflecting the construction process of the dock have been preserved.
