St. Basil's Cathedral

The Cathedral of Vasily the Blessed, commonly known as Saint Basil's Cathedral, is an Orthodox church in Red Square and one of the most popular cultural symbols of Russia. The building, now a museum, features 10 churches under one roof and is on the UNESCO World Heritage List. 

Ivan The Terrible ordered the construction of the cathedral in 1554 to commemorate his victories over the independent Tatar khanates of Kazan and Astrakhan. Stories and myths have it that Ivan ordered to blind the cathedral’s (unnamed) Italian architect so that its design could never be replicated.
