You step out onto blue flagstones, the ocean wind pressing against the battlements as gulls wheel over broad stone ramps. Narrow cobbled streets behind you give way to open ramparts: El Morro’s grassy glacis drops to the Atlantic while, a short walk away, San Cristóbal’s layered bastions loom like a city within a city. The sound here is wind, surf and the hollow echo of cannon-scarred walls.
