Cathedral of the Assumption. The grandfather of all the Kremlin churches, the Assumption Cathedral is the oldest and the biggest. Built in 1475 by Italian architect Aristotle Fiorovanti, this is where Ivan the Terrible was crowned Emperor in 1547 before becoming a stable for Napoleon's horses in 1812. Their soldiers made off with the chandeliers now hanging overhead, some weighing over 5 tonnes. The cossacks brought them back after they caught up with the light-fingered Frenchmen. In 1918 the last Easter service was held here. Services resumed in 1990.

Cathedral of the Archangel Michael. A relative youngster on the Kremlin church scene, this cathedral was erected in 1505 and holds the tombs of Russian rulers from Ivan I to Tsar Ivan V. It also has more of an Italian renaissance feel to it with its Corinthian gables and turrets and white stonework.

Annunciation Cathedral. This imposing cathedral, where Russia's Tsars were christened and married, was built by Pskov architects in 1482. The frescoes inside are considered to be some of the most valuable in Moscow given that prominent artists of the time including Andrey Rublyev (also buried here), Theophanes the Greek and Prokhor of Gorodetz all worked on them.

The Patriarch's Palace. Once the home of the Moscow Patriarch, this grand medieval building is now a museum where ecclesiastical treasures of the Orthodox church are on display as well as various precious tableware, furniture, jewellery and clothing used in the court of the medieval Tsars. The building also often houses temporary exhibitions.

Church of the Deposition of the Robes. Taking its name from an ancient festival where the Virgin's robes are transferred from Palestine to Constantinople (now Istanbul), this is a more modest cathedral nestled in a corner. Built in 1484 - 1485 by artists from Pskov, this church notably has stained glass windows. Along with some fine icons, inside you can also find wooden sculptures from the 15th century.

The Ivan the Great Bell Tower. The impressive 60 metre high tower was built between 1505 and 1508. The adjoining belfry was built 15 years later and contains some 20 bells. The biggest bell (the world's largest no less) however was too big to remain in its place and sits to the rear of the tower with a huge crack in it. In recent years the belfry has become home to a new high-tech exhibition which illustrates the history of the Kremlin's changing architectural styles. It is also now possible to climb up the tower (that's 137 steps to be exact) to admire the view over central Moscow and get a close up look at the bells.
