Church of the Savior on Spilled Blood was built in the late 19th century on the assassination site of Tsar Alexander II, who was killed by a terrorist’s bomb. The name refers to the blood of Tsar Alexander II of Russia, who was assassinated here, on the 13th of March 1881, by anarchist conspirators. In 1883 Tsar Alexander III began the construction of the church as a memorial to his father. Work progressed slowly and the church was not completed until 1907. Architecturally the church differs from Saint Petersburg's other churches and cathedrals that predominantly are built in Baroque and Neoclassic style. The Savior on Blood harks back to medieval Russian architecture in the spirit of romantic nationalism. It intentionally resembles the 17th-century Yaroslavl churches and the celebrated Saint Basil's Cathedral in Moscow. The church’s fascinating, colorful appearance is the result of the numerous materials used in its construction.For example, the bell tower is covered in 144 mosaic coats of arms, representing the regions and towns of Russia. The five domes are covered in jeweler’s enamel, and glazed ceramic tiles cover much of the exterior.
