My favorite building in St. Petersburg was the Cathedral of the Spilled Blood. The name refers to the place where Tsar Alexander II was assassinated in 1881. This spot became the site for this amazing church and inside there is still an area of exposed foundation to mark the exact location of Alexander II’s death. Alexander III held a competition for this church to be executed in a “purely Russian style of the 17th century.” Construction began in 1883 by the winner of the competition, the Russian architect Alfred Parland. Almost twenty-five years later, this church, including the interior with its magnificent mosaics with over twenty different Russian minerals and an ample amount of Italian marble, was completed.
