Castillo San Cristobal is a national heritage site we got a chance to visit while in San Juan. The fort was built by the Spanish in the 1700’s and originally covered almost 30 acres, barring access to the city with its walls. Some of the walls were removed much later to allow traffic to flow more freely, but the fort is still huge. It was at least three stories high, with sections cropping up here for troop quarters, there for officers, and areas for cannons, a dungeon, for sentries, etc. It’s a very impressive structure, with a long history, like Puerto Rico itself, of changing powers. The view from the windows and lookout areas was expansive and stunning, I eventually just put my phone away and made myself stop taking pictures so that I could just soak it in.
