Arecibo Observatory

The Arecibo Observatory was the world's largest radar radio telescope for over 60 years, until in 2016 a larger one was constructed in China. It was operated by the National Astronomy and Ionosphere Center of Cornell University for many years, and today makes for a great visit for science enthusiasts.

Capilla del Cristo

This small chapel is the embodiment of a centuries-old urban legend. It is said that the cliff-side abbey was built after an unknown horse rider galloped up the Old San Juan street and fell off the edge. It has been restored several times but still proudly shows signs of its age.

Casa Blanca Museum

This mansion, built in 1521, was designed to protect governor Ponce de León, who, ironically, never lived there. The Spanish militia seized the house in 1779. Almost 100 years later, the U.S. military took it over and kept it until 1966, after which it was transformed into a museum.
