1947 Map of Coamo NO

About this map

Coamo serves as the central hub for this 1940s topographic study, showing a concentrated grid of streets and buildings at the base of the mountains. The terrain is defined by the sharp descent of the Rio Coamo and the Rio Cuyon, which carve through the high elevations near Cerro Santa Ana. Small agricultural settlements like San Diego and Cacao appear as clusters of structures connected by winding roads through the interior hills. The map highlights the boundary between the Municipio de Coamo and the Municipio de Aibonito to the northeast. This preliminary edition, based on 1943 topography, captures the traditional land use and infrastructure of the region before significant mid-century modernizations changed the character of the mountain towns.
