The House of Soviets is the office building built in Stalinist style in the late 1930s. According to Soviet projects, the House of Soviets was planned to host the administration of Soviet Leningrad government. The location was chosen on undeveloped south outskirts of the city away from the downtown area which was prone to frequent floods. The construction was completed just before the Nazi invasion of Soviet Union at the beginning of World War II, and the building was never used for the intended purpose. In 1941, it was fortified and used as a local command post for Soviet Red Army during the Siege of Leningrad. Surviving reminders of that stronghold are small bunkers built from a reinforced concrete which still stand at several corners of the House of Soviets. Later, the building housed the Soviet research institute which focused on the design of electronic components for military objects. Among the notable engineers who worked there are two post-World War II defectors from the US, Alfred Sarant and Joel Barr. Currently, the office space in the building is rented out to various businesses.
A square in front of the House of Soviets is called Moscow Square (Moskovskaya Ploshad). During a construction of the subway station Moskovskaya in 1970, the square was remodelled and upgraded with a massive monument to Vladimir Lenin designed by Mikhail Anikushin. In 2006, several fountain features were added at the square.
References:The Chapel of St. Martin is the only completely preserved Romanesque building in Vyšehrad and one of the oldest in Prague. In was built around 1100 in the eastern part of the fortified outer ward. Between 1100 and 1300, the Rotrunda was surrounded by a cemetery. The building survived the Hussite Wars and was used as the municipal prison of the Town of the Vyšehrad Hill.
During the Thirty Years’ War, it was used as gunpowder storage, from 1700 to 1750, it was renovated and reconsecrated. In 1784, the chapel was closed passed to the military management which kept using it as a warehouseand a cannon-amunition manufacturing facility. In 1841, it was meant to be demolished to give way to the construction of a new road through Vyšehrad. Eventually, only the original western entrance was walled up and replaced with a new one in the sountren side. The dilapidating Rotunda subsequently served as a shelter for the poor.
