It is now Point State Park, within the Golden Triangle.","why_significant":"Control of this point was central to the French, English and American struggle for North America from the mid-18th century. Fort Duquesne's fall in 1758 broke French power in the Ohio country, and Fort Pitt protected settlers and the growing town of Pittsburgh. The site also held archaeological remains of Fort Pitt.","narrative":"Point State Park occupies the tip of land in Pittsburgh where the Monongahela and Allegheny Rivers join to form the Ohio. In the 18th century this ground was the strategic gateway to the Ohio Valley. Colonial forces began a fort here in 1754 on ground Lt. Col. George Washington had chosen, but the French seized it and completed Fort Duquesne. British and colonial troops under General John Forbes found it destroyed and abandoned in 1758. The British then built Fort Pitt nearby, which withstood Pontiac's uprising, served in the Revolution and was abandoned in 1790. The town of Pittsburgh grew under its protection. Railroad yards and commercial buildings once covered the site, but they have been cleared. Archaeological work in 1942-43 outlined Fort Pitt, and the lower ramparts of the music bastion are on permanent display. The Fort Pitt Museum stands on the Monongahela Bastion site, and a small brick blockhouse is the only original structure.","period_of_significance":"1754-1790","architect_builder":null,"architectural_style":null,"criteria":[],"status_note":"Described as in excellent condition and maintained as a public park, with Fort Pitt's excavated ramparts, a museum and a surviving blockhouse.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:59:01.683259-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/66000643_NHL.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/66000643/ea93bae098-800.webp","url_1600":"https://nationalhistoricalregister.com/media/66000643/ea93bae098-1600.webp","licence":"CC BY-SA 2.0","author":"John","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Point_State_Park_in_Fall.jpg\" rel=\"noopener\">John</a>, <a href=\"https://creativecommons.org/licenses/by-sa/2.0\" rel=\"license noopener\">CC BY-SA 2.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Point_State_Park_in_Fall.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71994395","wikipedia":"https://en.wikipedia.org/wiki/Point_State_Park","wikidata":"https://www.wikidata.org/wiki/Q7208170"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/allegheny-county/forks-of-the-ohio-66000643/"}
