It now serves as a county museum.","why_significant":"The building was the final American office of the Holland Land Company, a Dutch-financed enterprise that surveyed and sold lands across western New York and northwestern Pennsylvania. Through this office Joseph Ellicott directed surveying, road layout, land sales and credit, and the company's work played a major role in settling the northern frontier east of the Great Lakes.","narrative":"Built in 1815 on the north bank of Tonawanda Creek in Batavia, New York, this limestone building served as the third and last American office of the Holland Land Company. Joseph Ellicott, the company's agent on site, oversaw its construction. The structure measures 47 by 36 feet and has a pedimented portico with four stone pillars, a fanlight doorway, two dormers on each side of the gable roof and fanlights in the gable ends. The company, formed in 1796 by six Dutch banking houses, held millions of acres in western New York and northwestern Pennsylvania. From Batavia, Ellicott laid out roads, divided townships into lots, contracted sales, collected installments and granted deeds and mortgages. The company's operations continued until about 1856. The building later became a county museum. Two rear additions, one from the 1940s and one from 1970, are the main alterations; the original building keeps much of its early appearance.","period_of_significance":"1800-1899","architect_builder":"Joseph Ellicott","architectural_style":null,"criteria":[],"status_note":"Occupied and in use as a Genesee County museum; later additions at the rear (1940s and 1970) are not considered contributory.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:50:38.894287-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/66000521_NHL.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/66000521/bf52f40a5f-800.webp","url_1600":"https://nationalhistoricalregister.com/media/66000521/bf52f40a5f-1600.webp","licence":"CC BY-SA 3.0","author":"The original uploader was Pollinator at English Wikipedia.","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Holland_land_8911.jpg\" rel=\"noopener\">The original uploader was Pollinator at English Wikipedia.</a>, <a href=\"http://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:Holland_land_8911.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75315762","wikipedia":"https://en.wikipedia.org/wiki/Holland_Land_Office","wikidata":"https://www.wikidata.org/wiki/Q5881001"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/genesee-county/holland-land-office-66000521/"}
