Havana, Cuba's capital city is home to a prodigious wealth of colonial and 19-century architectural masterpieces. These are slowly and painstakingly emerging from neglect brought on by the U.S. economic blockade. Havana's harbor and the city's Revolutionary Square provide ideal backdrops for understanding Cuba from the late 1950s to the present, why it so appealed to Ernest Hemingway, how African roots influence the city's culture, and why even now it is a mecca for international tourists.
