Museo Anahuacalli

This guide to Museo Anahuacalli in Mexico City follows Diego Rivera's obsession with pre-Hispanic pottery, masks, and clay figures, bought up by the tens of thousands even as his wife warned there was no money left to eat. It traces the fortress of black volcanic rock he built to house them, construction stalling for lack of funds and Frida Kahlo writing to government contacts to try to save it. Rivera died in 1957 with the building still unfinished around his collection, floors bare and windows empty.
