1953 Map of Comerio

About this map

Comerio and Cidra anchor this early 1950s survey of Puerto Rico's central mountain region, where the deep valleys of the Rio de la Plata and Río Bayamón define the landscape. The map captures an era of developing educational infrastructure, noting specialized facilities like the Escuela Superior de Comerio and several rural second-unit schools including the Escuela Segunda Unidad de Palomas. The reservoir of Lago de Cidra stands as a prominent geographic feature, surrounded by numerous named mountain peaks such as Cerro La Tiza and Cerro Santa Bárbara. The intricate network of winding roads and numerous 'Quebradas'—small streams like Quebrada Doña Elena and Quebrada Conventó—illustrate the complex topography that historically isolated these inland communities before modern transportation improvements.
