Campeche also has many brightly colored buildings reflective of Caribbean tastes. As might be expected in a seaport town, Campeche has an abundance of fresh seafood prepared in every conceivable manner including some flavored with tasty Caribbean spices.

Some of these secret passageways are said to date back to Mayan times
