Moskovsky Prospekt (Russian: Моско́вский проспе́кт, Moskovsky Avenue) is a 10 km-long prospekt in Saint Petersburg, Russia. It runs from Sennaya Square and Sadovaya Street, to the Victory Square, where it splits into Pulkovo Highway and Moscow Highway. It crosses Fontanka River, Zagorodny Prospekt, Obvodny Canal, and Ligovsky Prospekt. It is named for and leads to Moscow.
The prospekt began to develop as a part of the major route connecting the city with Moscow and south provinces. The original name of the prospekt was Tsarskoselskaya Doroga (Route to Tsarskoe Selo) since it leads to imperial estates in Tsarskoye Selo. In the 1770s, marble mileposts were installed along the way; many have survived to this day. Another notable fact about the prospekt is that it coincides with the so-called Pulkovo Meridian.
Among historic buildings along the prospekt are Saint Petersburg State Institute of Technology, the New Smolny Convent with the adjacent Novodevichy Cemetery. The intersection with Ligovsky Prospekt features the Moscow Triumphal Gate designed by Vasily Stasov and constructed in 1834-1838 to commemorate the victory in the Russo-Turkish War of 1828-1829. After the Russo-Turkish War, 1877-1878 the prospekt was renamed Zabalkansky (i.e., Transbalkanian), to memorialize the crossing of the Balkans by the Russian army.
The southern stretch of the prospekt features an ensemble of buildings built in the distinctive Stalinist style in the 1930-1950s. One of the most notable buildings among those is the House of Soviets (1941) which was a military stronghold and command post during the Siege in World War II.
