About this map

Fort Devens dominates the western landscape of this mid-century survey, its expansive military footprint including the Fort Devens Airport, a Rifle Range, and industrial facilities like Sewage Disposal plants. The surrounding townships exhibit a complex New England landscape of established academic institutions and water-driven geography. To the north, Groton is home to the Lawrence Academy and the sprawling Groton Fairgrounds, while the Nashua River and Squannacook River frame the western boundary.

Transport and education define the local economy, with the Boston and Maine Railroad converging at Ayer and serving smaller stops like Harvard Station. Intellectual and historical landmarks are scattered throughout, from the Harvard University Observatory in the south to the historic Shaker Village and Pingryville. This record captures the transition of the region from a collection of rural mill and farm towns to an area defined by significant military and educational centers.
