New Hampshire’s seacoast may be just 18 miles long, but what it lacks in length, it makes up for with centuries of fascinating maritime history. Portsmouth developed along the banks of the Piscataqua River to become the state’s colonial capital and a center of trade and shipbuilding. Portsmouth Harbor’s 1771 lighthouse was the first lighthouse established in the American colonies north of Boston. A few miles offshore, Native Americans were fishing and hunting at the archipelago known as the Isles of Shoals for centuries before the islands were developed by European fishermen and settlers in the 1600s, and a lighthouse was established at the southernmost island in 1821. Inland, three wooden lighthouses were built on Lake Sunapee in the late 1800s to guide steamships full of vacationers to their destinations around the lake. All of these locations have stories to tell of dedicated keepers and their families, shipwrecks, rescues, and much more.
