Later in the 20th century, the building served as the Archivo General de la Nación and from 1982 as the Museo Nacional de Arte. The plaza in front of the building is named after Manuel Tolsá, who created the statue of Carlos IV there, also known as El Caballito. Today almost all of the building is used to house the permanent collection of MUNAL with the Reception Hall and the Patio de los Leones used for events such as concerts, book-signings and press conferences.
