Construction began in 1755 under chief engineer Michel Chartier (later Marquis de Lotbiniere).","why_significant":"Located at the junction of Lake Champlain and Lake George, the fort was the key to Canada and the Hudson Valley from 1755 to 1777 and saw more of the English-French and American-English struggles than any other post. It is described as the finest reconstructed example of an advanced 18th-century European-design fortress in the United States.","narrative":"Fort Ticonderoga occupies a rocky promontory where Ticonderoga Creek meets Lake Champlain, near the north end of Lake George. The French began building it as Fort Carillon in 1755, using a Vauban-style plan with four corner bastions, two demi-lunes, and stone barracks around a sunken parade ground. The site controlled the route between Canada and the Hudson Valley. Montcalm's French force repulsed a large British attack in 1758, but General Amherst captured the fort in 1759. Ethan Allen and the Green Mountain Boys took it in 1775, and cannon from the fort were later hauled to the siege of Boston. In 1777 Burgoyne placed artillery on Mount Defiance, and the Americans evacuated. The fort fell into ruin until Stephen Pell began reconstruction in 1908 on the original foundations. Today it serves as a museum, with French outer lines, a trader's village site, and the Jardin du Roi nearby.","period_of_significance":"1755-1757","architect_builder":"Marquis de Lotbiniere (Michel Chartier)","architectural_style":"Fortress based on the designs of Vauban, adapted to the rocky ridge","criteria":[],"status_note":"Restored beginning in 1908 and used as offices, museum and display areas; owned and administered by the Fort Ticonderoga Association.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:50:38.871919-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/66000519_NHL.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/66000519/5a0ece8ab1-800.webp","url_1600":"https://nationalhistoricalregister.com/media/66000519/5a0ece8ab1-1600.webp","licence":"CC BY-SA 3.0","author":"Mwanner","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Fort_Ticonderoga,_Ticonderoga,_NY.jpg\" rel=\"noopener\">Mwanner</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:Fort_Ticonderoga,_Ticonderoga,_NY.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75315748","wikipedia":"https://en.wikipedia.org/wiki/Fort_Ticonderoga","wikidata":"https://www.wikidata.org/wiki/Q1438776"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/essex-county/fort-ticonderoga-66000519/"}
