The Palace of Fine Arts in Mexico City was supposed to be finished by 1910, in time for the centenary of Mexican independence. It was not. The Italian architect Adamo Boari ran into a familiar local problem: the building started sinking unevenly. Then the Revolution began, and construction stopped. Boari died before it was completed.

When the Mexican architect Federico Mariscal finally finished it in the 1930s, the country had changed entirely. Boari's white marble exterior was kept. The interiors were remodelled in Art Deco, threaded with Pre-Columbian references. A theatre for the elite became a public arts complex, its walls covered in murals by Diego Rivera, Orozco, and Siqueiros.

VoiceMap's self-guided audio tours use the Palacio de Bellas Artes to trace how the Revolution transformed Mexico's cultural ambitions, from a Díaz-era monument to European taste into something altogether more Mexican.
