The Saint Basil's Cathedral, also known as the Cathedral of Intercession of Theotokos on the Moat, is one of the trademarks of the capital of Russia. It was erected in 1555–1561 by architects Barma and Postnik on the order of Ivan IV of Russia to commemorate the capture of Kazan and Astrakhan. Legend held that once the construction was finished, Ivan blinded the architects so that they could not recreate the masterpiece elsewhere. The cathedral was named after Russian Orthodox saint, Basil Fool for Christ, feared by tsar Ivan the Terrible himself for Basil's diatribes. Currently, the cathedral is a part of the UNESCO World Heritage.
