Both geographically and historically, the Kremlin stands at the very heart of Moscow. Sited on the northern bank of the Moscow River, its doors have opened to Russian tsars, Bolshevik revolutionaries and leaders of the Soviet Union and today it is the seat of the Russian Government. The Kremlin walls, surmounted by 20 towers, envelop beautiful fifteenth- and sixteenth-century cathedrals and churches in Cathedral Square, the Great Kremlin Palace, the Patriarch's Palace and the Palace of Congresses.

Cathedral Square has three magnificent cathedrals standing along its perimeter that include the Cathedral of the Assumption, Archangel Cathedral, Cathedral of the Annunciation and the Faceted Hall. Also in the square is the sixteenth-century Ivan the Great Bell Tower, the tallest structure in the Kremlin, and at the foot of it lies the cracked Tsar Bell.
