Charlestown, New Hampshire

Fort at Number 4

About this city

Also known as: Fort at Number 4

Charlestown is a deeply historic, architecture-rich river city beautifully built along the flat alluvial plains of the Connecticut River on New Hampshire's western border with Vermont. Established meticulously in 1735 as 'Fort at Number 4,' the settlement served for decades as the absolute northernmost frontier military outpost protecting colonial New England from fierce French and Native American raids. Today, the town expertly preserves its grand heritage, featuring an exceptionally wide, tree-lined main street lined with majestic 18th-century Federal and Greek Revival historic mansions.
