Portsmouth Harbor Light

The Portsmouth Harbor Light on the New Hampshire coast near the Seabrook Station nuclear power plant has guided ships for more than two centuries, longer than all but a few lighthouses in North America. President George Washington inspected the wood tower that replaced the original Portsmouth Light - a lantern hung from a pole at a colonial fort in 1771. The current 48-foot-tall structure, consisting of bolted iron plates, was completed in 1877.
