Cuba's second-oldest museum (after the Museo Bacardí in Santiago) offers a selection of weird artifacts, including a strangulation chair from 1830, a face mask of Napoleon, the tail of Antonio Maceo's horse, Cuba's largest collection of snails and, last but by no means least, some preserved fleas – yes fleas – from 1912.
The museum is set in a lovely colonial building and staffed with knowledgeable official guides.
