Williamsburg, MAInc. 1735
Williamsburg is a small town in the foothills west of Northampton, with the village of Haydenville as its secondary center. Both villages have compact centers with older homes and small commercial buildings. The Mill River runs through the town, and the 1874 Mill River Flood — one of the deadliest dam failures in American history — shaped the community's development.
For property professionals, Williamsburg is a modest market in the Northampton area orbit, with village-center properties and surrounding rural residential development. The Mill River creates flood zone considerations.
