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:Celje Castle was once the largest fortification on Slovenian territory. The first fortified building on the site (a Romanesque palace) was built in the first half of the 13th century by the Counts of Heunburg from Carinthia on the stony outcrop on the western side of the ridge where the castle stands. It had five sides, or four plus the southern side, which was a natural defence. The first written records of the castle date back to between 1125 and 1137; it was probably built by Count Gunter. In the western section of the castle, there was a building with several floors. Remains of the walls of this palatium have survived. In the eastern section, there was an enclosed courtyard with large water reservoirs. The eastern wall, which protects the castle from its most exposed side, was around three metres thicker than the rest of the curtain wall. The wall was topped with a parapet and protected walkway.
