 It houses a collection representing the history of Mexican art from the late pre-Hispanic era to the early 20th century.It is recognizable by Manuel Tolsá's large equestrian statue of Charles IV of Spain who was the monarch just before Mexico gained its Independence.It was originally in the Zocalo but it was moved to several locations, not out of deference to the king but rather to conserve a piece of art, according to the plaque at the base.
