Pokrovsky Cathedral (St. Basil’s Cathedral) on the Red Square is a great creation of Russian architects. It was founded in the middle of 16th century to commemorate the accession of Kazan khanate to the Moscow kingdom and is unequalled. The gorgeous temple is a gem of world architecture, a symbol of Moscow and Russia. Today Pokrovsky Cathedral is both museum and temple. The Russian Orthodox Church holds public liturgies here on Sundays and at the days of major Orthodox holidays.
