It is part of the Springfield, Massachusetts Metropolitan Statistical Area. New Salem was first settled in 1737 and was officially incorporated in 1753, named for the settlers from Salem that founded the town. The geography of New Salem benefited greatly from the construction of the Quabbin Reservoir. Prior to its building, New Salem, which has always been the southeastern corner of Franklin County, did not extend much further south than the village of Cooleyville, now along U.S. Route 202. However, with the formation of the reservoir, the town received all lands above the water line between the two forks of the reservoir, as it was the only land connection to the peninsula. With its southern borders now following former branches of the Swift River, New Salem now includes most of the former town of Prescott, and parts of Greenwich and Enfield. All the lands gained by the annexation were once part of Hampshire County.
