You will walk cross the square and through Alexander's Garden along the Kremlin wall to the Kremlin entrance. We'll begin our tour of the Moscow Kremlin complex and the Armory Museum. The Moscow Kremlin is the center of Moscow and of Russian politics. A large walled castle situated on Borovitsky Hill, the Kremlin is the former home of the tsars and the seat of Russian government. It dates mainly from the 15th century, although the first wooden fort was built on the site in 1150. The highest building within the Kremlin is the Ivan the Great Bell Tower with two golden domes. At the side of the tower is the Tsar Bell, the world's largest at 202 tons, which was cast in 1730. During a fire in 1737 an 11 ton piece cracked off the rim. The Cathedral of the Assumption built in 1479 was used for the coronation of the tsars. The Cathedral of the Archangel, completed in 1509, was used for burying them; forty-six tsars were laid to rest within the cathedral. Also inside the Kremlin we find the Armory, Russia's oldest museum and one of its most impressive. Built in the 18th century and surrounded by 800 captured Napoleonic cannons, the Armory Museum contains a display of jewels and court regalia, armor and weapons from the Romanov dynasty.
