1947 Map of San Juan

About this map

San Juan and its surrounding barrios are depicted here during a period of significant mid-century urban expansion, just as the island was transitioning toward modernization. The map captures the dense historic core at La Fortaleza and Pta del Morro, while highlighting the growth of residential and institutional zones such as Barriada Eleanor Roosevelt and the sprawling Universidad de Puerto Rico campus. This survey provides a critical look at the social infrastructure of the era, marking the locations of several island-wide institutions including the Sanatorio Insular, Penitenciaria Insular, and Manicomio Insular.
