The Seven Sisters is a group of Moscow skyscrapers designed in the Stalinist style. They were built from 1947 to 1953, in an elaborate combination of Russian Baroque and Gothic styles, and the technology used in building American skyscrapers. The seven are: Hotel Ukraina, Kotelnicheskaya Embankment Apartments, the Kudrinskaya Square Building, the Hotel Leningradskaya, the Ministry of Foreign Affairs, the main building of the Moscow State University, and the Red Gates Administrative Building.
The first Soviet skyscraper project, Palace of the Soviets, was interrupted by the German invasion of 1941, at which point the steel frame was scrapped in order to fortify the Moscow defense ring, and the site was abandoned. In 1946, Stalin personally switched to another idea - construction of a chain of reasonably-sized skyscrapers not tarnished by the memories of the Comintern. As Nikita Khrushchev recalled Stalin's words, "We won the war ... foreigners will come to Moscow, walk around, and there's no skyscrapers. If they compare Moscow to capitalist cities, it's a moral blow to us". Nothing is known about selection of construction sites or design evaluation; this process (1947–1948) was kept secret, a sign of Stalin's personal tight management. The choice of architects is a clear indicator of a rotation in Stalin's preferences. Old professionals like Shchusev, Zholtovsky etc., were not involved. Instead, the job was given to the next generation of mature architects. In 1947, the oldest of them, Vladimir Gelfreikh, was 62. The youngest, Mikhail Posokhin, was 37. Individual commissions were ranked according to each architect's status, and clearly segmented into two groups - four first class and four second class towers. Job number one, a Vorobyovy Gory tower that would become Moscow State University, was awarded to Lev Rudnev, a new leader of his profession. Rudnev received his commission only in September 1948, and employed hundreds of professional designers. He released his draft in early 1949. Dmitry Chechulin received two commissions.
In April 1949, the winner of the Stalin Prize for 1948 was announced. All eight design teams received first and second class awards, according to their project status, regardless of their architectural value. At this stage, these were conceptual drafts; often one would be cancelled and others would be altered.
All the buildings employed over-engineered steel frames with concrete ceilings and masonry infill, based on concrete slab foundations (in the case of the University building - 7 meters thick). Exterior ceramic tiles, panels up to 15 square meters, were secured with stainless steel anchors. The height of these buildings was not limited by political will, but by lack of technology and experience - the structures were far heavier than American skyscrapers.
The effect of this project on real urban needs can be seen from these numbers: in 1947, 1948, 1949 respectively, Moscow built a total of 100,000, 270,000, and 405,000 square meters of housing.
The skyscrapers project exceeded 500,000 square meters (at a higher cost per meter) In other words, the resources diverted for this project effectively halved housing construction rates. On the other hand, the new construction plants, built for this project (like Kuchino Ceramics), were fundamental to Khrushchev's residential program just a few years later.
Boris Iofan made a mistake placing his draft skyscraper right on the edge of Sparrow Hills. The site was a potential landslide hazard. He made a worse mistake by insisting on his decision and was promptly replaced by Lev Rudnev, a 53-year-old rising star of Stalin's establishment. Rudnev had already built high-profile edifices like the 1932-1937 Frunze Military Academy and the 1947 Marshals' Apartments (Sadovaya-Kudrinskaya, 28), which earned the highest credits of the Party.
Lev Rudnev set the building 800 meters away from the cliff. The opening ceremony was followed by less glorious events - building camps for Gulag laborers, mostly German prisoners of war. A so-called Site-560 (Строительство-560), run by Gulag, supervised the workforce that reached 14,290. While the construction was ongoing, some inmates were housed on the 24th and 25th levels to reduce transportation costs and the number of guards required. A story, possibly apocryphal, exists about inmates who tried to escape the tower on self-made plywood gliders. Another apocryphal story asserts that the MGU foundation requires permanent freezing (otherwise it will slide into the river) and the basement is occupied by huge cryo freezer. Actually, the foundation is stable, and the 'freezer' is an ordinary centralised air conditioner. The main tower, which consumed over 40,000 metric tons of steel, was inaugurated September 1, 1953. At 240 metres tall, it was the tallest building in Europe from its completion until 1990. It is still the tallest educational building in the world.
In 1934, the Commissariat for Heavy Industries initiated a design contest for its new building on Red Square (on the site of GUM). A last showcase for constructivists, this contest didn't materialize and GUM still stands. In 1947, the nearby medieval Zaryadye district was razed to make way for the new 32-storey, 275-meter tower (the numbers are quoted as in the 1951 finalized draft). It is sometimes associated with the Ministry of Heavy Machinery, the same institution that ran a contest in 1934. However, in all public documents of this time its name is simply the administrative building, without any specific affiliation. Likewise, association with Beria is mostly anecdotal. The tower, designed by Chechulin, was supposed to be the second largest after the University. Eventually, the plans were cancelled at the foundation stage; these foundations were used later for the construction of the Rossiya Hotel (also by Chechulin, 1967, demolished 2006-2007).
Hotel Ukraina by Arkady Mordvinov and Vyacheslav Oltarzhevsky (leading Soviet expert on steel-framed highrise construction) is the second tallest of the "sisters" (198 meters, 34 levels). It was the tallest hotel in the world from the time of its construction until the Peachtree Plaza Hotel opened in Atlanta, Georgia in 1975. Construction on the low river bank meant that the builders had to dig well below the water level. This was solved by an ingenious water retention system, using a perimeter of needle pumps driven deep into ground. The hotel reopened its doors again after a 3-year-renovation on April 28, 2010, now called Radisson Royal Hotel, Moscow, with 505 bedrooms and 38 apartments.
This 172 meter, 27 story building was built between 1948 and 1953 and overseen by V. G. Gelfreikh and M. A. Minkus. Currently, it houses the offices for the Ministry of Foreign Affairs for the Russian Federation. The Ministry is covered by a light external stone wall with projecting pilasters and pylons and, according to architectural critic Maria Kiernan, was inspired by a neo-gothic New York city hospital. Its interior is splendidly decorated with stones and metals. According to the 1982 biography of Minkus, draft plans were first drawn up in 1946 and ranged from 9 to 40 stories. In 1947 two designs were proposed: one utilized layered setbacks while the other called for a more streamlined construction which culminated into a blunt rectangular top. The second proposal was accepted but as the Ministry's completion neared, a metal spire, dyed to match the building's exterior (and presumably ordered by Stalin), was hastily added to tower's roof, assimilating its silhouette with those of the other Sisters.
Originally known simply as the Leningradskaya Hotel, this relatively small (136 meters, 26 floors, of which 19 are usable) building by Leonid Polyakov on Komsomolskaya Square is decorated with pseudo-Russian ornaments mimicking Alexey Shchusev's Kazansky Rail Terminal[citation needed. Inside, it was inefficiently planned. Khruschev, in his 1955 decree "On liquidation of excesses..." asserted that at least 1000 rooms could be built for the cost of Leningradskaya's 354, that only 22% of the total space was rent-able, and that the costs per bed were 50% higher than in Moskva Hotel. Following this critique, Polyakov was stripped of his 1948 Stalin Prize but retained the other one, for a Moscow Metro station. After a multi-million dollar renovation ending in 2008, the hotel re-opened as the Hilton Moscow Leningradskaya.
Another of Chechulin's works, 176 meters high, with 22 usable levels, the Kotelnicheskaya Embankment Building was strategically placed at the confluence of the Moskva River and Yauza River. The building incorporates an earlier 9-story apartment block facing Moskva River, by the same architects (completed in 1940). It was intended as an elite housing building. However, very soon after construction, units were converted to multi-family kommunalka (communal apartments). Built in a neo-gothic design, though also drew inspiration from Hotel Metropol.
Designed by Mikhail Posokhin (Sr.) and Ashot Mndoyants. 160 metres high, 22 floors (17 usable). The building is located on the end of Krasnaya Presnya street, facing the Sadovoye Koltso and was primary built with high-end apartments for Soviet cultural leaders rather than politicians.
