San Juan: Spanish forts on the Caribbean

The Castillo San Felipe del Morro, a six-level fortress built starting in 1539 on the most exposed point of the peninsula, resisted English and Dutch attacks before becoming, centuries later, a UNESCO World Heritage site.

The Castillo San Cristóbal, the largest Spanish fort ever built in the Americas, covers nearly eleven hectares with a system of underground galleries designed to resist even after the outer walls fell.

The Fortaleza, the governor's residence since the sixteenth century, is the oldest continuously-used executive seat in the entire American continent.

The colonial houses of Calle Fortaleza and adjacent streets, painted in the pastel tones typical of the old city, today host art galleries and small cafes behind Spanish wrought-iron balconies.

El Morro and San Cristóbal were built to repel enemy fleets, not tourists: the same underground galleries designed for war are today visited in silence, without any siege having tested them again.

The pastel facades of Calle Fortaleza, lighter in tone, instead tell the story of San Juan that continued to live within those same walls long after the end of colonial wars.
