Caguana Indigenous Ceremonial Park

The stones here were placed around 1270 AD by the Taíno people — ceremonial ball courts and petroglyph-carved monoliths arranged, archaeologists now believe, in alignment with specific astronomical events. The largest concentration of petroglyphs in the Antilles is here, carved into the monoliths that line the bateyes. The Institute of Puerto Rican Culture manages the site and operates an on-site museum; the museum reopened in 2024 with more than 200 archaeological pieces. It is a National Historic Landmark, and one of the most significant pre-Columbian sites in the Caribbean.
