Part of the San Juan National Historic Site –  The largest fortification built in the New World, a UNESCO World Heritage Site.

Castillo San Cristobal, with its sprawling outer defenses, was built over 150 years to protect El Morro and the city from land attack.  Inspired by such attacks by rivals England (1598) and Holland (1625), it was designed by the Irish-born Chief Engineer Thomas O’Daly.  O’Daly served Spain because Spain was an enemy of Ireland’s enemy England.

Castillo San Cristobal is the biggest European fortification in the Americas.  It lost some outworks when part of the city wall was torn down in 1897 to expand the city of San Juan.”  Construction began in 1634 and completed by 1790.  Castillo San Cristobal covers 27 acres on the eastern gate of the islet of San Juan.
