Old San Juan - San Cristóbal Fort

(Local Name: Castillo de San Cristóbal) A National Historic Site, Castillo de San Cristóbal (San Cristóbal Fort) began construction in 1634 and was completed in 1771. Castillo de San Cristóbal is one of the largest defenses built in the Americas, rising 150ft/46m and covering 27ac/11ha of land. It is a fascinating place to walk around and explore, you just never know what interesting things you will find. Strategically planned to confuse enemies, Castillo de San Cristóbal features five independent units connected by moat and tunnel, each designed to be self-sufficient should the others fall.
