The Church of the Savior on Spilled Blood in St Petersburg was built on the site where Alexander II was wounded resulting in his death in March 1881. While travelling passed this area a gernade was thrown under the carriage of Alexander II, it was a secondary blast that mortally wounded him. Construction began in 1883 under Alexander III, his son, and finished in 1907 under Nicholas II.
