Got there half an hour early so quickly whizzed round the Museo Mural Diego Rivera. Oddly, it hosts just one Rivera painting, but it's a big one: Sueño de una tarde dominical en la Alameda Central (Dream of a Sunday Afternoon in the Alameda Central), a 15m-long mural painted in 1947. It originally hung in the Hotel Del Prado but when that building was destroyed in the 1985 earthquake, they moved it to this new museum, which must have been quite an operation.
The fresco takes us on a Sunday walk through Alameda Park and represents three principal eras of Mexican History: the Spanish Conquest, the Porfiriato Dictatorship, and the Revolution of 1910, in chronological order from left to right. In the centre is Diego Rivera at the age of ten being led by the hand by La Calavera Catrina, a skeleton figure parodying vanity, and behind him is (inevitably) Frida Kahlo.
The rest of the museum is given over to temporary exhibitions, currently one by Rosendo Soto (1912-94).
