Charlestown began as Plantation Number 4 in 1735, the northernmost British outpost on the Connecticut River. Settlers raised the Fort at Number 4 in 1744. Captain Phineas Stevens held it against a three-day siege in 1747. Governor Benning Wentworth rechartered the town as Charlestown in 1753. Sixty-three buildings along Main Street now sit on the National Register. Master builder Stephen Hassam shaped many of them after the 1842 fire. Federal, Greek Revival, and Gothic Revival homes line the street, backed by farmhouses and capes on the ridges. About 100 miles from Boston, this river town still moves at its own pace.
Here’s how our crews turn a plan into a finished wall you’ll be proud of.
