Named after Emperor Alexander I, who ruled Russia between 1801 and 1825 (during the Napoleonic Wars), it was designed by the French-born architect Auguste de Montferrand and built between 1830 and 1834. The monument is 155 feet 8 inches tall and is topped with a statue of an angel holding a cross (the face of the angel is said to be modeled on the face of Emperor Alexander I). The body of the column is made of a single monolith of red granite, which stands 83 feet 6 inches high and about 11 feet 5 inches in diameter. It is a terrific feat of engineering that this enormous column, weighing an incredible 1,322,760 pounds (600 tons), was erected in under 2 hours without the aid of modern cranes and engineering machines.
