|Kremlin is the Russian word for "fortress", "citadel" or "castle" and refers to any major fortified central complex found in historic Russian cities. This word is often used to refer to the best-known one, the Moscow Kremlin, or 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 this is not a part of the Moscow Kremlin. The Kremlin is Russia's "Symbol" just like in the U.S. the symbol is the White House, or Capitol building. The name Kremlin (or Kreml) has been allocated to various Soviet Navy vessels during construction. In each case, the name was changed prior to commissioning. Vessels which have briefly carried this name included Admiral Kuznetsov and Ulyanovsk. Within the Palace of the Castle Church Cathedral Museum contains armament arsenal tower castle tower with many sales and sharp dome 65 feet high wall around the palace. Length of nearly 3 km.
