From the outbreak of King Philip’s War in 1675 until the conclusion of the French and Indian War in 1763, much of northern New England was under an ongoing threat of violence along its frontier. Nearly all of the English settlement in Maine was pushed back to a few towns nearest New Hampshire, and many villages, including Dover, suffered devastation and massacre.
Indeed, officials ordered many residents to construct fortified garrison houses, like this reproduction along Cider Hill Road in York, Maine, where families could retreat for armed protection when an alarm was sounded.
