The eastern side of ploshchad Dvortsovaya (Palace Square) is formed by the huge arc of this building; its form and size give the square its unusual shape. During tsarist rule this was the site of the army headquarters and the ministries of foreign affairs and finance. Created by the architect Carlo Giovanni Rossi in the neoclassical style and built between 1819 and 1829, the huge assemblage is actually two structures connected by a monumental archway. Together they form the longest building in Europe. The arch itself is another commemoration of Russia's victory over Napoléon. Topping it is an impressive 33-foot-tall bronze of Victory driving a six-horse chariot, created by the artists Vasily Demut-Malinovsky and Stepan Pimenov. The passageway created by the arch leads from the square to St. Petersburg's most important boulevard, Nevsky prospekt. Part of the Hermitage, the building has a permanent display on its history and architecture, plus temporary exhibits of local and international artwork.
