The name Kremlin means "fortress", and is often used as a metonym to refer to the government of the Soviet Union (1922–1991) and its highest members (such as general secretaries, premiers, presidents, ministers, and commissars), in the same way that the metonym Élysée Palace refers to the President of the French Republic, the White House refers to the Executive Office of the President of the United States and Number 10 Downing Street or Whitehall refers to the Offices of Prime Minister of the United Kingdom and the British Government. It is still used in reference to the government of the Russian Federation and even the Russian President's official website is Kremlin.ru. "Kremlinology" refers to the study of Soviet and Russian policies.
A kremlin (Russian: кремль, tr.kreml; IPA: [ˈkrʲemlʲ], fortress; same root as in kremen (Russian: кремень, tr.kremen; IPA: [krʲɪˈmenʲ], flint)) is a major fortified central complex found in historic Russian cities. This word is often used to refer to the most famous one, the Moscow Kremlin, or metonymically to the government that is based there. Outside Russia, the name Kremlin is sometimes mistakenly thought of as being Saint Basil's Cathedral because of its distinctive environment, although the cathedral is not a part of the Moscow Kremlin.
Russia's presidential administration is located in the Moscow Kremlin. During the Cold War the government of the USSR was located in the Moscow Kremlin but now the Russian government occupies a building outside it.
