Today marks the 450th anniversary of the completion of St. Basil’s Cathedral in Moscow, Russia. Taking six years to construct and being finished in 1561, the cathedral was commissioned to celebrate the defeat of the Khanate of Kazan by Tsar Ivan IV (also known as Ivan the Terrible). It sits at the heart of Moscow on the edge of Red Square and is a truly magnificent and unique structure with its height, onion-shaped domes, and bright colors. It survived Napoleon, was secularized by the Soviets in 1929, and is a state-owned museum today. Below are some of the pictures I took of it during my visit to Moscow in 2007.
