Palace Square is considered to be the city’s main square and serves as an excellent example of how different architectural styles can be combined in a most elaborate and aesthetically pleasing way. On the northern side of the square stands the picturesque Baroque Winter Palace (built in 1754-62). Across the square, on the southern side, stands the classical yellow-and-white building of the former Imperial Army General Staff (built between 1819 and 1829 by the Italian architect Carlo Rossi). The building encircles the Southern side of the square and combines a central arch, designed as a Triumphal Arch after the ancient architecture of the Classical World, through which you can reach Nevsky Prospekt. In the middle of the square is the Alexander Column. The monument was erected after the Russian victory in the war with Napoleon’s France.
