The Alexander Column was designed by the French-born architect Auguste de Montferrand, built between 1830 and 1834 with Swiss-born architect Antonio Adamini, and unveiled on 30 August 1834 (St. Alexander of Constantinople's Day). The monument is claimed to be the tallest of its kind in the world at 47.5 m (155 ft 8 in) tall and is topped with a statue of an angel holding a cross, as a triumphal column it may be the highest but the Monument to the Great Fire of London is a freestanding column 62 m high.
