San Juan National Historic Site

San Juan National Historic Site

Preserved in Puerto Rico, San Juan National Historic Site is one of the NPS historical parks where walking the site adds something a textbook cannot provide. San Juan National Historic Site preserves stories of great ambition and aspirations. Countries fought for control of this tiny yet strategic island for centuries.

Generations of soldiers have lived and worked within the forts. Visitors today are as inspired by these stories as they are by the beauty of the architecture and the ingenuity of design and engineering of this World Heritage Site.

As a historical park, San Juan National Historic Site exists because the place, not just the documents, deserves preservation. Plan for a slower pace than a typical sightseeing day.
