Located just outside San Juan is the archaeological remains of the first Puerto Ricans. The Tainos people lived on the island until the 15th century when the Spanish arrived and they died off from disease and subjugation. What remains is a glimpse into how these people lived. You can see petroglyphs etched in granite, artifacts uncovered during archaeological excavations and see the ceremonial plazas used by the Tainos.
These courts, called bateyes, are believed to be part of the most sacred Taíno area in the West Indies.Knowledgeable visitors seek out La Mujer de Caguana, a rare petroglyph of a woman with the legs of a frog, wearing an elaborate headdress!
A small museum contains Indian artifacts, archaeological exhibits and a botanical garden featuring the plants the Taínos harvested for food, such as sweet potatoes, cassava, corn and yautía. The trees that were used for building materials, such as mahogany, ceiba, tabonuco, and ausubo can be seen in their natural setting.
