The Eighth Sister is the unbuilt project for a skyscraper in Zaryadye, Moscow. It would have been the eighth sister to the group of Stalinist skyscrapers known as Seven Sisters. The architect was Dmitry Chechulin. Original 1947 plans included an eighth tower, which would have been among the tallest buildings in the world. Following Joseph Stalin's death in 1953, it was decided that the projected structure would overshadow the Moscow Kremlin and Chechulin's 1967 Rossiya Hotel was erected on the spot. The hotel was demolished in 2006, and the Zaryadye Park was inaugurated on 9 September 2017. Project description The final design of the administrative building in Zaryadye was completed and published in 1949, at which time its two authors, the architect Dmitry Chechulin and the engineer Iosif Tigranov, became winners of the Stalin Prize. A 15-hectare plot was allocated for the construction of an administrative building in Zaryadye. It was bounded by Red Square to the west, Kitaygorodsky Proyezd to the east and Moskvoretskaya Embankment to the south. The authors of the project had the difficult task of blending the 32-storey high-rise building into the historic buildings of the centre of Moscow. The administrative building in Zaryadye, along with other high-rise buildings, was to serve as a symbol of the greatness of socialist Moscow and the Stalinist era. The structure was symmetrical and had a stepped structure. Similar to the Building of the USSR Ministry of Foreign Affairs, the administrative high-rise started with five-storey buildings in with the surrounding low-rise buildings. The buildings were located diagonally concerning one another and were equipped with lifts. In the lower part of the building, there were to be about 2,000 workrooms and offices for the staff of the department. The upper part of the building was separated from the lower part by two intermediate levels. The first of them was to be three storeys high, and the next, a six-storey one, served as a kind of transition to the high-rise tower. This construction, topped with a gilded polyhedral tent with a spire and an emblem with symbols of the USSR, was the main part of the building. The upper floors of the tower were used as a showroom with four pavilions. The radial system of the administrative building contributed to the convenient organisation of the internal premises, the even distribution of wind loads and the strength of the structural links, which increased
