Federation Tower

The Federation Tower (Russian: Башня Федерация, romanized: Bashnya Federatsya) is a complex of two skyscrapers built on the 13th lot of the Moscow International Business Center (MIBC) in Moscow, Russia. The two skyscrapers are named Tower East or Vostok (Russian: Восток; literally means "East") and Tower West or Zapad (Russian: Запад; literally means "West").

The supertall skyscraper Tower East (Vostok) is currently the second-tallest skyscraper in Europe and Russia after Lakhta Center, the tallest building in Moscow, and the 55th-tallest building in the world. Zapad is a shorter skyscraper than Vostok and is the 11th-tallest building in Russia. The complex stands on the 13th lot, which has an area of 439,154 square meters.

The complex was designed by architecture companies nps+partner and Schweger Associated Architects. The complex started construction in 2005, with Zapad completed first in 2008 with a height of 242 meters (794 feet). As a result of the Great Recession, construction of the complex stopped until August 2011, and Vostok was completed on December 7, 2017 with a height of 373,7 meters (1,226 feet). In late 2014, Vostok surpassed the South Tower of OKO, which it is also part of the MIBC, as the tallest skyscraper of Russia and Europe. A spire was to be also built which would have extended the complex's height to 450 meters (1,476 feet) as well as provided an
