Built between 1883 and 1907 at a colossal price, the gorgeous church was erected in the memory of Tsar Alexander II, who was fatally wounded by anarchists at the same site. Inside is just as majestic as its fantastic exterior; every conceivable surface is coated in astonishing mosaics of saints and icons. After having been ransacked in the Russian revolution, used as a morgue in WWII and as a vegetable warehouse in Soviet times, the Cathedral of the Resurrection of Christ – to give it its official title – has thankfully been restored to its former glory.
