1555 – 1561
Saint Basil’s Cathedral, commonly known as The Cathedral of Vasily the Blessed, in Moscow, Russia, was built by Ivan the Terrible from 1555-1561 and commemorates the capture of Kazan and Astrakhan. The building, now a museum, is officially known as the Cathedral of the Intercession of the Most Holy Theotokos on the Moat. I visited Moscow in November 2004. I saw Lenin’s body in the Mausoleum. It was beautiful city.
