1947 Map of Corozal NE

About this map

The rugged interior of Puerto Rico’s north-central region is defined by the winding course of the Río La Plata and the deep valleys carved by the Mavilla and Prieto rivers. During the early 1940s, this landscape was characterized by a dense network of mountain trails and scattered rural dwellings, connected by essential social hubs like the Escuela Segunda Unidad Quebrada Arenas and the Escuela Segunda Unidad de Palmarejo. The map reveals the intricate municipal borders where the Municipio de Toa Alta, Municipio de Corozal, and Municipio de Naranjito meet. This topographical study emphasizes the agricultural and residential patterns of the era, where life followed the contours of the Quebrada and Cañas waterways before modern development altered the rural character of the highland municipalities.
