It served as a place of refuge for Mohawk Valley settlers during the War for Independence. The Battle of Klock's Field, fought October 19, 1780, took place in the adjacent fields.","narrative":"Fort Klock is a fieldstone house on a hillside near the north bank of the Mohawk River, east of St. Johnsville, New York. Johannes Klock built it in 1750 as a fortified frontier residence and fur trading post, replacing an earlier dwelling on the site. The L-shaped, one-story building has two-foot-thick walls pierced with loopholes for muskets, and its cellar encloses a spring. During the War for Independence a log stockade was added, and neighbors gathered here when raids threatened. The nomination describes it as a fine surviving example of the fortified houses that protected Mohawk Valley settlers. On October 19, 1780, the Battle of Klock's Field was fought nearby between Sir John Johnson's and Joseph Brant's forces and pursuing American militia. The structure is largely original, though its chimneys and porch have been rebuilt. A restoration committee repaired it in the 1960s and opens it to summer visitors as a museum.","period_of_significance":"1750, 1775-83 (18th Century)","architect_builder":"Johannes Klock (builder/original owner)","architectural_style":null,"criteria":[],"status_note":"Good condition; restored in the 1960s by the Fort Klock Restoration Committee and open to visitors as a museum during the summer season.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:50:38.649248-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/72000859_NHL.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/72000859/93f06bce74-800.webp","url_1600":"https://nationalhistoricalregister.com/media/72000859/93f06bce74-1600.webp","licence":"CC BY-SA 4.0","author":"Lvklock","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:FortklockSept1991.jpg\" rel=\"noopener\">Lvklock</a>, <a href=\"https://creativecommons.org/licenses/by-sa/4.0\" rel=\"license noopener\">CC BY-SA 4.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:FortklockSept1991.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75315805","wikipedia":"https://en.wikipedia.org/wiki/Fort_Klock","wikidata":"https://www.wikidata.org/wiki/Q5471434"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/montgomery-county/fort-klock-72000859/"}
