On the south side of Plaza de la Patria, the red-and-pink stone Palacio de Gobierno is Aguascalientes' most noteworthy colonial building. Once the mansion of colonial baron Marqués de Guadalupe, it dates from 1665 and has a striking courtyard with two levels of murals. Many government buildings in Mexico have wall murals but these ones really are something special.
Noteworthy among them is the mural depicting the 1914 convention by the Chilean artist Osvaldo Barra. Barra, whose mentor was Diego Rivera, also painted the mural on the south wall, a compendium of the forces that forged Aguascalientes.
