Eighth Sister

The Eighth Sister is the unbuilt project for the Zaryadye skyscraper in Moscow. It would have been eighth sister to the group of seven postwar Stalinist skyscrapers in Moscow, Russia. The architect was Dmitry Chechulin.

Original 1947 plans included an eighth tower, which would have been among the tallest buildings in the world. Following Stalin's death, it was decided that the projected structure would overshadow the Moscow Kremlin and Chechulin's 1967 Rossiya Hotel was erected on the spot. The skyscraper, with some modifications, was instead built in Warsaw (see Palace of Culture and Science, Warsaw).

The Triumph-Palace, completed in 2003, now the second tallest building in Europe and 59th in the world, is unofficially referred to as the Eighth Sister.
