The Monument to Nicholas I (Russian: Памятник Николаю I) is a bronze equestrian monument of Nicholas I of Russia on St Isaac's Square (in front of Saint Isaac's Cathedral) in Saint Petersburg, Russia. Unveiled on July 7th June 25th 1859, the six-meter statue was a technical wonder of its time. It was the first equestrian statue in Europe with only two support points (the rear hooves of the horse), the only precedent being the 1852 equestrian statue of U.S President Andrew Jackson.
