The Palace of Belle Artes, Mexico City. This lovely art deco museum contains some superb murals by Diego Rivera, David Siquerios (a Stalinist who once led a plot to assassinate Leon Trotsky, who had been given refuge in Mexico, partly as a result of Rivera's lobbying of the government. The plot failed, but you can still see the bullet holes in the walls of Trotsky's house. Stalin eventually got his way when one of his henchmen stuck an ice pick in his skull) and others. The day we visited the museum was also home to the dead body of a recently deceased Mexican artist who was lying in an open coffin in the middle of the central atrium. I have some photos of him but am led to believe that posting them on the web wouldn't be in the best of taste. I bet the Mexicans wouldn't mind.
