Don Luis Hernandez, a sugar cane worker and farmer from the Toma Vieja section of Tibes in Ponce, made charcoal as a part-time job. While searching for wood to make for charcoal, he discovered remnants of indigenous cultures that had been buried over time and were uncovered by the flooding. Tibes is the most important archeological site in the Caribbean. It represents the continuous habitation of indigenous people more than 1,000 years before Columbus encountered the New World.(centro ceremonial indígena tibes, ponce...).He found pieces of bone and shells and ceramic fragments. He felt he had discovered a great secret and he initially kept it to himself. Although he realized that the objects he had discovered belonged to Puerto Rico's Indian past, he never realized that he had discovered one of the most important archeological sites in the Antilles. Little by little the Vega de Tani began to reveal its secrets, for the benefit of Puerto Ricans and the scientific community, producing the most important archeological site of its type in the Caribbean. They discovered the oldest Antillian Indian ceremonial complex yet uncovered in Puerto Rico, consisting of nine ball courts and three ceremonial plazas. Within its boundaries is the largest indigenous cemetery yet discovered - consisting of 186 human skeletons, most from the Igneri and the rest from the Pre-Taino Cultures.
