The lighthouses of Puerto Rico are a study in themselves, having years of stories to tell about architecture, weather, battles, colonization, settlement and maritime adventures. There are approximately 15 lighthouses around the island, and 11 of them are still active. The oldest is the faro, or lighthouse, at Castillo de Morro in San Juan, which was established in 1846, and most of the others were established within the next 50 years. In 1981, all of the lighthouses were placed on the National Register of Historic Places, so many of them continue to be maintained for use and for tourism. This list includes some of the most beautiful lighthouses to tour when you visit Puerto Rico.
