Havana is located at the coast, but it also has a big bay that is used for the harbor. This bay has a small passage to come in. The city with the old town is located on one side of this entrance and an old castle is located on the other side: Castillo de les Tres Reyes Magos del Morro and the lighthouse Faro O’Donell o del Morro de La Habana.
Unfortunately we were unable to visit the castle, because of the book fair inside the castle. I already wrote about it in a past post.
