About this map

San German serves as the focal point of this 1930s survey, illustrating the dense concentration of educational and religious institutions that defined the town during this era. The Polytechnic Institute occupies a prominent campus just west of the town center, while numerous rural schools like Escuela Manuel F Rossy and Escuela Jose de Diego are scattered throughout the surrounding hills of Los Peñones. The agricultural landscape is clearly delineated by traditional landholdings, including Hacienda Luisa and Hacienda Desengaño, which emphasize the sugar-driven economy centered around Central Eureka.

Transportation infrastructure is dominated by the American Railroad of Puerto Rico, which winds through the valleys and services stops like Estacion Lajas. To the south, the terrain drops into the Valle de Lajas, where the Laguna de Cartagena and the marshes of Cienaga el Anegado dominate the hydrology. The map captures a transition point in Puerto Rican development, where established colonial-era haciendas coexisted with modernizing rail networks and a growing public school system.
