The Church of the Savior on Spilled Blood (Russian: Церковь Спаса на Крови, Tserkovʹ Spasa na Krovi) is a Russian Orthodox church in Saint Petersburg, Russia which currently functions as a secular museum and church at the same time. The structure was constructed between 1883 and 1907. It is one of Saint Petersburg's major attractions

Construction began in 1883, during the reign of Alexander III, two years after the assassination of his father, Alexander II. The church was dedicated as a memorial in his honor. It is estimated that the total cost of construction reached 4.5 million rubles. The building was completed in 1907, under the rule of Nicholas II. Financial support came from the Imperial family, along with numerous private contributors.

The church occupies a prominent location along the Griboedov Canal, flanked by paved roads on both sides. On March 13, 1881 (March 1 in the Julian calendar), a bomb was thrown at Alexander II’s carriage by an anarchist while it traveled along the canal embankment. Although the explosion left the tsar unharmed, he stepped out to confront the attacker. At that moment, a second conspirator hurled another bomb, killing himself and fatally wounding the tsar. Severely injured and bleeding, Alexander II was taken to the Winter Palace, where he died shortly thereafter.

Initially, a temporary shrine was erected on the site of the attack, while plans and fundraising for a permanent memorial were set in motion. To ensure the new church encompassed the precise location of the assassination, the canal was reportedly narrowed so that the section of roadway where the bombing occurred could be enclosed within the church structure. A richly decorated shrine, designed as a ciborium, was built at the end of the church opposite the main altar, marking the exact spot of the tsar’s death. It features inlays of topaz, lazurite, and other semi-precious stones, providing a vivid contrast to the plain cobblestones of the original road, which remain visible in the floor of the shrine.
