San Juan Bay (Spanish: Bahía de San Juan) is the bay and main inlet adjacent to Old San Juan in northeastern Puerto Rico. It is about 3.5 miles (5.6 km) in length, the largest body of water in an estuary of about 97 square miles (250 km2) of channels, inlets and eight interconnected lagoons.

Fortín San Juan de la Cruz (Fort Saint John of the Cross), known locally as El Cañuelo, was built on Isla de Cabras in the Palo Seco barrio of the municipality of Toa Baja, at the western end of the entrance to San Juan Bay, in Puerto Rico.

The Superintendent of Lighthouses' Dwelling is an early 20th-century hacienda-style building located in the San Juan Coast Guard Station of La Puntilla in the Marina subdistrict (subbarrio) of Old San Juan. Although the exact date of construction is not known, deteriorated plan drawings of the old United States Naval Base that previously occupied the site of the coast guard station show that the building might have been built either in 1903 or 1908 as part of the regional lighthouses' depot. The building and its surroundings were identified as the Lighthouse Reservation at La Puntilla, with one of its earliest occupants, U.S. Lighthouse Superintendent J. P. Dillon signing and approving plan drawings by the Corps of Engineers. Although the architectural style is inspired in Spanish Revival haciendas found in both private and public buildings the United States, the specific "hacienda-style", as described by the U.S. government survey, was not indigenous nor common in Puerto Rico at the time, and the building and surrounding landscape represents the first design of its kind in the island after 1898.

It was listed by UNESCO in 1983 as part of the World Heritage Site "La Fortaleza and San Juan National Historic Site". During the 1640 reconstruction, the chapel of Santa Catalina, which originally stood outside the walls, was integrated into the structure's walls, resulting in the alternate name Santa Catalina's Castle.
