At the center of Suvorovskaya Ploshchad, between the Field of Mars and the Neva River, stands this monument to Alexander Suvorov, the great Russian military commander. Under his command, the Russian army won a series of great victories in the Russo-Turkish War of 1787-1791, and in the Russo-Austrian campaign against Napoleon's forces in 1799, which included Suvorov's legendary crossing of the Alps.
Immediately after that incredible campaign, it was decided to erect a monument to Suvorov in the Russian capital. Unfortunately, he died before the statue was officially unveiled in 1801. In the romantic fashion of the era, Suvorov is represented as the Roman god of war, Mars. He stands holding a sword and shield, the shield guarding a three-sided altar on which have been placed the crowns of Naples and Sardinia and the papal tiara, representing the Italian lands Suvorov defended against Napoleon.
This monument was the first in St. Petersburg to be designed and built exclusively by Russian craftsmen. The sculptor was Mikhail Kozlovskiy, and he was assisted by the architect Andrey Voronikhin. The monument was originally erected on the bank of the River Moyka not far from the Mikhailovskiy Castle but in 1818 on the suggestion of Carlo Rossi was moved to the center of the newly created Suvorovskaya Ploshchad.
