This Historic Structure Report describes the historic Nauset Beach lighthouses, known as the Three Sisters, as they appeared during inspection in February and June of 1983. It also provides the historical and architectural information related to the structure. Because they were included in a thematic nomination of Massachusetts lighthouses to the National Register of Historic Places, a treatment plan was proposed to preserve the structures. The National Park Service intended to move the Three Sisters to a new site, restore their linear arrangement, and restore the lighthouses in accordance with the historic structure report for interpretation to park visitors. The significance of the Three Sisters is related to their role in coastal navigation, lighthouse history, local history, and as landmarks. The structures are tapered circular towers of wood frame construction with white shingle siding. They are also known as the Beacon and the Twins from their periods of use as parts of summer cottages. Although the Twins lost their lights and lanterns sometime between 1910 and 1918 and the Beacon, light intact, had been out of service since 1923, together they may constitute the only surviving set of triple lights in the United States.
