The Highland Light (previously known as Cape Cod Light) is a working lighthouse on the Cape Cod National Seashore in North Truro, Massachusetts. It is the oldest and tallest lighthouse on Cape Cod...In 1797, a station authorized by George Washington was established at this point on the Cape, with a wood lighthouse to warn ships about the dangerous coastline between Cape Ann and Nantucket. It was the first light on Cape Cod. In 1833, the wood structure was replaced by brick... In 1857 the lighthouse was declared dangerous and demolished, and the current brick tower was constructed, with a first order Fresnel lens from Paris...In 1932 the lamp was upgraded to a 1000 watt beacon...The present location of the lighthouse is not the original site. It was in danger of falling down the cliff due to beach erosion, so the structure was moved 450 feet (140m) to the west. Source: Wikipedia
