Although none of its 18th century lights survive, it still marks an important navigational point within the Nantucket National Landmark District. It is stated to meet criteria A and C.","narrative":"Brant Point Light Station occupies a sandy spit at the western side of the entrance to Nantucket Harbor. Its principal feature is the active 1901 tower, a white shingled cylinder about 26 feet tall, reached by a long elevated wooden walkway over the beach. Inside, the tower keeps a modernized Fresnel lens, a ten-sided lens room and an iron balcony with a simple original-looking railing. Nearby are an 1856-57 brick keeper's house with an attached, now dismantled tower, and an oil house, all counted as contributing parts of the complex. Lighthouses have stood at this point since a 1746 town vote, though earlier towers burned or blew down, and the 1795 cession to the United States involved the sixth light. The 1854 rebuilding used one of the first Fresnel lenses in the country. The station is valued for its integrity and its role in the history of navigation aids in Massachusetts, and for marking the first structure seen on approaching Nantucket.","period_of_significance":null,"architect_builder":null,"architectural_style":null,"criteria":["A","C"],"status_note":"Listed as unmanned and active; the 1901 tower is active, while the 1856-57 tower is dismantled and abandoned, with the Coast Guard planning to convert it to a communications and watchstanders room.","vacant_flag":null,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:13:01.366314-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/39/7923/63792339/content/electronic-records/rg-079/NPS_MA/87002029.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/87002029/c84c87e0b6-800.webp","url_1600":"https://nationalhistoricalregister.com/media/87002029/c84c87e0b6-1600.webp","licence":"CC BY-SA 3.0","author":"Denimadept","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Brant_Point_Light,_oblique.jpg\" rel=\"noopener\">Denimadept</a>, <a href=\"https://creativecommons.org/licenses/by-sa/3.0\" rel=\"license noopener\">CC BY-SA 3.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Brant_Point_Light,_oblique.jpg"},"district":{"nrhp_refnum":"66000772","name":"Nantucket Historic District","url":"https://nationalhistoricalregister.com/districts/massachusetts/nantucket-historic-district-66000772/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/63792339","wikipedia":"https://en.wikipedia.org/wiki/Brant_Point_Light","wikidata":"https://www.wikidata.org/wiki/Q4957614"},"indexable":true,"url":"https://nationalhistoricalregister.com/massachusetts/nantucket-county/brant-point-light-station-87002029/"}
