Fort Constitution Historic Site
Portsmouth Harbor fortifications occupy the site of a pivotal 1774 raid
Artwork inspired by White Mountain School
Portsmouth Harbor fortifications occupy the site of a pivotal 1774 raid. Ruined walls, later military layers, a lighthouse neighbor, and harbor traffic compress colonial resistance and coastal defense into one small point. Rather than relying on one headline feature, the experience gains depth from the contrast among fort walls, Portsmouth Harbor Light, and harbor channel.
Read the site chronologically so later masonry does not get mistaken for the Revolutionary fort. Access passes an active Coast Guard station; parking is very limited and surfaces are rough. Visitors who include harbor channel gain a fuller sense of place than those who stop after seeing only fort walls.
