The Moscow Triumphal Gate, a Neoclassical triumphal arch built mainly in cast iron and erected in 1834–1838 to commemorate the Russian victory in the Russo-Turkish War, 1828-1829.
This part is interesting: “In 1936, during the period of Joseph Stalin’s concentration of power over the Leningrad leadership, the historic gate was dismantled with plans to move them to Moscow Square Park.
“Later, during the Siege of Leningrad in 1941, when the German army approached the outskirts of Leningrad, the cast iron blocks of the gate were used in creating an anti-tank defensive structure near the southern border of the city, helping to repel the Germans during the siege.
“The gate was restored from 1958 to 1960. A group of restorers managed to recreate most of the lost sculptural details of the monument. The new columns, friezes and cornices were cast at the Kirov factory in Leningrad.”
