About this map

La Fortaleza stands at the western tip of the islet, overlooking the entrance to the Bahía de San Juan during this late 1940s survey. The map details a city in transition, where the historic fortifications near Pta del Morro give way to the dense urban expansion of Santurce and the academic grounds of the Universidad de Puerto Rico. Along the coastline, the American Railroad winds past the U. S. Naval Reservation and into the industrial heart of Cataño across the water.

Institutional growth is evident through the inclusion of several insular facilities, such as the Manicomio Insular and the Sanatorio Insular. Residential developments like Barriada Eleanor Roosevelt and Hato Rey push southward into the hills, while the ancient heritage of the island is marked by Las Ruinas de Caparra, identifying the earliest Spanish settlement site near the modern roads of Desvío San Patricio.
