The "Monumento" has three parts: the Tower ("Torre") or mast, 70 metres high, which commemorates the Revolution of May 1810 and houses Manuel Belgrano's crypt in its base; the Civic Courtyard ("Patio Cívico"), which symbolizes the effort of the organization of the state (the Courtyard is used for massive open-air shows), and the Triumphal Propylaeum ("Propileo Triunfal"), representing the Nation as organized after the 1853 Constitution. Under the Propylaeum there is the Honour Room for the Flags of America (where the flags of all American nations are displayed).
