Castillo San Cristóbal is a historic fortress located in Old San Juan, Puerto Rico. Constructed by the Spanish between 1634 and 1790, it stands as the largest fortification built by Spain in the New World. The fort was designed to protect the city from land-based attacks, complementing the seaward defenses provided by Castillo San Felipe del Morro.
