Groton Dunstable Regional
Groton and Dunstable are two adjacent towns in northern Middlesex County, about 40 miles northwest of Boston, sharing a regional school district that serves both communities. Groton, the larger of the two, is a historic town founded in 1655 and known for its rural character, conservation lands, and the prestigious Groton School, a private preparatory academy established in 1884. The area maintains a blend of suburban residential neighborhoods, working farms, and protected open spaces, with both towns retaining much of their New England agricultural heritage despite gradual suburban growth.
