1958 Map of Cayo Icacos

About this map

Cabo San Juan defines the northeastern tip of Puerto Rico, where the lighthouse at Faro de Cabo San Juan overlooks the transition from the Atlantic Ocean to the Sonda de Vieques. This maritime landscape is characterized by the intricate chain of reefs and islets known as La Cordillera, stretching eastward through Cayo Icacos, Cayo Lobos, and the isolated Cayo Diablo. To the south, the waters of Rada Fajardo are protected by significant landmasses like Isla Palominos and Isla de Ramos. The presence of hazards such as Arrecife Roncador and Arrecife Corona Carrillo underscores the importance of the historic Faro for navigation through the Pasaje de San Juan. The coastal geography is further marked by the enclosed Laguna Grande and the prominent headlands of Cabezas de San Juan, providing a clear view of the region's hydrography as recorded in the mid-20th century.
