Punta Tuna Lighthouse

Punta Tuna Light is a historic lighthouse located in the southeast of the town of Maunabo, Puerto Rico on a narrow promontory at the southeasternmost point of the island. It was first lit in 1892 and automated in 1989. The light was a third-order lighthouse that served as the primary light connecting the island's southern and eastern lights system. The design was drawn and laid out by Joaquin Gisbert in 1890.
