Every region of Puerto Rico has at least one landmark worth a detour outside Old San Juan — from Ponce’s Parque de Bombas firehouse to the Arecibo Observatory site. These seven standout regional landmarks are each rooted in a different region’s history and culture.
| Landmark | Municipality | Significance |
|---|---|---|
| Parque de Bombas | Ponce | An iconic red-and-black striped 1882 firehouse, now a museum and one of the most photographed buildings on the island |
| Serrallés Castle | Ponce | Spanish Revival mansion of the Don Q rum family, overlooking the city |
| Caguana Ceremonial Ballpark | Utuado | A pre-Columbian Taíno ceremonial and ballgame site with petroglyphs |
| Punta Tuna Lighthouse | Maunabo | 19th-century lighthouse on a remote southeast headland |
| Los Morrillos Lighthouse | Cabo Rojo | Cliffside lighthouse over the island’s dramatic southwest coast |
| Arecibo Observatory site | Arecibo | Former home of one of the world’s most famous radio telescopes; visitor center remains open |
