Centro Ceremonial Indígena de Tibes

Hurricane Eloise did the archaeology. In 1975, the storm's floodwaters stripped topsoil from the northern outskirts of Ponce and exposed what turned out to be the oldest ceremonial complex yet uncovered in the Antilles — ball courts, ceremonial plazas, and the largest indigenous cemetery found in the region, containing 186 human skeletons from the Igneri and Taíno cultures. The Igneri built it; the Taínos inherited it. The museum opened in 1982. The site is still being excavated.
