Built in the 1700s as Fort William and Mary, Fort Constitution was the subject of Paul Revere's first ride and, some say, the first overt act of the Revolutionary War. The fort is not staffed, nor are there brochures or other information available. Access is through a short walk across the Coast Guard station parking lot.
Small, picturesque Sandy Beach, 10 minutes from Portsmouth, has the U.S. Coast Guard Station at one end and a large seaside park, New Castle Common, at the other end.
