Fidel Castro’s revolution left fascinating attractions in its wake. There are sites of military importance that have fallen out of use, like the Moncada Barracks, an attraction that now houses a museum and a school. At the El Morro Historic Park you can see a fort built by the Spanish, which has also been transformed into a museum. The Morro-Cabaña Military Park is a fort that was originally built to ward off English pirate attacks. See Cuba’s colonial history in the neighborhood of Trinidad, where historians and artists have worked to keep the buildings picturesque. Near Trinidad you can also visit the Valley de los Ingenios, the site of Cuba’s oldest sugar plantations.
