The Cathedral of Christ the Saviour is a Russian Orthodox cathedral in Moscow, Russia, on the northern bank of the Moskva River, a few hundred meters southwest of the Kremlin. With an overall height of 103 meters (338 ft), it is the third tallest Orthodox Christian church building in the world, after the People's Salvation Cathedral in Bucharest, Romania, and Saints Peter and Paul Cathedral in Saint Petersburg, Russia.
The current church is the second to stand on this site. The authentic church, built during the 19th century, took more than 40 years to build and was the scene of the 1882 world premiere of the 1812 Overture composed by Tchaikovsky.
