1957 Map of Comerio

About this map

Comerio and Cidra anchor this mid-century portrait of Puerto Rico’s central mountainous region, showing a landscape defined by the winding course of the Río de la Plata and the waters of Lago Cidra. The map reveals a dense network of barrios and communities, including Bayamoncito, Santa Bárbara, and Vegas, connected by winding insular routes. A strong emphasis on local education is evident through the presence of institutions like the Escuela Superior de Comerío and the Escuela Vocacional Eugenio María de Hostos. This 1957 survey, later updated with photorevisions, provides a critical look at the infrastructure of the era, from the Central Cayey settlement in the southeast to the Planta de Tratamiento de Aguas Negras near the reservoir. The topography is dominated by prominent peaks such as Cerro La Tiza and Cerro Magueyes, illustrating the steep terrain that dictated the layout of small settlements and agriculture.
