At 81 meters, this building was Moscow's tallest for nearly 350 years. Viewed from some distance, the tower looks like a giant whitewashed lipstick. Three octahedral tiers carry a short cylinder on top, crowned with a glistening golden onion dome. The 'Ivan the Great' in the tower's name is not referring to Ivan (IV) the Terrible as popularly believed, but to his grandfather Ivan III who ruled from 1462 to 1505.
