Havana has a lot to offer but when you're in the city, be sure to check out Old Havana. Some people refer to it as a little piece of Spain in the Caribbean and it definitely lives up to that reputation. This part of the city is considered a world heritage site, full of Andalusian-style buildings as well as cathedrals and palaces. If you look closely, you can even see the cannon holes used for defense in the 17th and 18th centuries.
