1938 Map of Alto Sano

About this map

Agricultural life in late 1930s Puerto Rico is centered on the valley of the Rio Culebrinas and the Rio Grande. The landscape is dominated by a high density of named haciendas and fincas, including Hacienda Mata, Hacienda Lamberti, and Finca San Miguel, reflecting an economy deeply rooted in local landholdings. Industrial activity is anchored by Central La Plata in the northeastern quadrant, while the social infrastructure is marked by dozens of rural schools such as the Pesante Rural School and the Escuela Benjamin Franklin. The intricate terrain is defined by numerous peaks like Cerro Pelao and Cerro Pichon, with the Barrio Espino Medical Center serving as a vital point of interest for the surrounding rural population. This survey captures a moment of intensive rural settlement and education expansion just prior to the mid-century shifts in the island's interior.
