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 perhaps shares a same root as kremen (кремень [krʲɪˈmʲenʲ], "flint").
