On the far southeast coast is the Castillo de San Pedro de la Roca, a certified world heritage site constructed during the first half of the 17th century. This castle sits on the top of rugged cliffs and offers stunning views of the surrounding ocean. This was by design - fear of pirates is part of what necessitated building the castle in the first place. Today, it's a great place for taking pictures, particularly if you're willing to wander through the palisades and turrets.
