1957 Map of Comerio

About this map

Comerio and the winding Río de la Plata define the high-relief interior of Puerto Rico in this mid-century survey. The landscape is marked by a transition from the urban density of the Pueblo and Comerio town center to the agricultural and mountainous barrios of Dona Elena, Naranjo, and Honduras. Infrastructure for a growing population is evident, including the Planta de Tratamiento de Aguas Negras near Lago Cidra and several educational institutions like the Escuela Superior de Comerio.
