Located north of the Palacio Nacional on the other side of Calle Moneda, the Antiguo Palacio del Arzobispado houses the Museo de la Secretaría de Hacienda (Tax Ministry Museum). It boasts a fine collection of Mexican art, mainly containing works given by artists to pay their taxes, as was their right. Don't miss the paintings by Diego Rivera and Rufino Tamayo and the murals by José Gordillo.
