It sits on a hilltop in a small park overlooking the St. Lawrence River.","why_significant":"The nomination calls it the only surviving example of its type in northern New York, though not completely intact. It was powered by wind because water power was not readily available, and it is cited as an example of the resourcefulness of early residents. It has also become a revered symbol of Morristown.","narrative":"Built in 1825 by Hugh McConnell, this round stone windmill at 143 Morris Street in Morristown was constructed as a gristmill. Its builders chose wind power because water power was not readily available. The coursed rubble walls rise about 40 feet and measure 77 feet around at the base. The vanes and internal gears have been removed, and the stairs and present roof date from the 1940s. A wooden stair leads to a lookout platform at the top, and several millstones remain on the property. The mill stands on a hilltop in a small park above the St. Lawrence River, surrounded by houses. It is described as the only surviving example of its type in northern New York; of four similar mills built in Canada, only two remain in comparable condition. Over time it served as a jail and as an Air Warning Systems observation post in World War II. The village owns it, and it is open on summer weekends. Local backers hope to rebuild the gears for educational use.","period_of_significance":null,"architect_builder":"Hugh McConnell (builder)","architectural_style":null,"criteria":["A","C"],"status_note":"Village-owned lookout in a small park, open to the public on summer weekends; condition rated fair, with no known threats.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:50:42.938349-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/82004689.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/82004689/c2fbd83fca-800.webp","url_1600":"https://nationalhistoricalregister.com/media/82004689/c2fbd83fca-1600.webp","licence":"CC BY-SA 3.0","author":"JERRYE &amp; ROY KLOTZ MD","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:STONE_WIND_MILL.jpg\" rel=\"noopener\">JERRYE &amp;amp; ROY KLOTZ MD</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:STONE_WIND_MILL.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75314678","wikipedia":"https://en.wikipedia.org/wiki/McConnell%27s_Windmill","wikidata":"https://www.wikidata.org/wiki/Q15252517"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/st-lawrence-county/stone-windmill-82004689/"}
