Located in the Upper Schoodic Peninsula sub-region of Maine's Downeast Acadia region, the Municipality has had several incarnations as Waukeag, New Bristol, and later Sullivan; and once included nearby communities of Hancock, Sorrento, and what would later be (parts of Gouldsboro Point TWP, Tunk Lake TWP, the Schoodic Foothills, Hog Bay, and various other districts over time divided off) Township 7, South & Middle Districts. Once home to abundant granite quarries, the Town of Sullivan is now regarded as a residential community for nearby Ellsworth and Mount Desert Island, Maine. Located along US Rte 1, Taunton River, and Hog Bay, Sullivan is home to a slough of reversing tidal falls and many scenic turnouts that dot the Schoodic National Scenic Byway along the Upper Schoodic Peninsula.
Document 3: List of lighthouses in Massachusetts: This is a list of all lighthouses in the U.S. state of Massachusetts as identified by the United States Coast Guard. Enumeration of the lighthouses in this state is complicated by the number of multiple tower stations and replacement of older towers, with the Brant Point Light station having had nine towers, two of which survive. At present there are forty-seven active towers, of which eleven are privately maintained; thirteen are standing but inactive, seven have been replaced with skeleton towers, thirteen have been destroyed or removed, and one tower has been moved to another state. The oldest station, Boston Light, established in 1716, was the first lighthouse built in the colonies, and the current tower at that station, built in 1783, is the oldest survivor in the state and the second oldest in the nation, and was the last lighthouse automated in the United States. The last station established was at the Buzzards Bay Entrance Light in 1961 (since replaced by an automated light on a steel tripod), but in 1986 the 1818 Great Point Light was rebuilt and relit, making it the last tower constructed in the state. The tallest towers in the state are the two Cape Ann Light towers, but the highest focal plane is at the Hospital Point Range Rear Light, which is located in the steeple of the First Baptist Church of Beverly.
