Fodor's Expert Review Castillo de San Salvador de la Punta

On a point (hence, the name) directly across from El Morro, La Punta took 11 years to build (1589–1600), under the supervision of the same Italian military engineer—Juan Bautista Antonelli—responsible for its sister fortress. The two forts are so close, it's said that voice communication is possible in calm weather. In the early 17th century, a heavy chain was stretched between them, sealing the port at night and during attacks. Today the fortress has an even more romantic role in the city's unfolding drama: it's a favorite spot for lovers. At the time of writing, it was closed to the public due to ongoing renovations, but walking around the outside still makes for an impressive view.
