A kremlin (Russian: кремль, tr. kreml’, IPA: [ˈkrʲemlʲ], "castle", or "citadel") is a major fortified central complex found in historic Russian cities. This word is often used to refer to the most famous, the Moscow Kremlin, or metonymically to the government that is based there.
The word is probably of Slavic-Tartar origin, and may share the same root as kremen (кремень [krʲɪˈmʲenʲ], "flint").
