It holds 169 contributing and 34 noncontributing resources, mostly houses, farmsteads and mill-related buildings from the mid-19th to early 20th century.","why_significant":"The district shows how a rural farming area along Prospect Street grew into a concentrated manufacturing and farming neighborhood powered by the Mill River. Firearms and machine-shop businesses, such as the Shattuck gun shop and Porter-McLeod lathe works, drew immigrant workers and shaped its housing. Its farmsteads, tobacco barns and the 1830 Borden Baseline survey marker add to its significance.","narrative":"This district in Hatfield, Massachusetts, sits on the western edge of the Connecticut River floodplain, where the Mill River drops 16 feet over a natural falls. Prospect Street runs north to south through it, crossed by School, Bridge and Chestnut Streets. The district includes 169 contributing resources: houses, farmsteads, barns, mill buildings, structures and an object. Architectural styles range from Greek Revival through Italianate and Queen Anne to Colonial Revival, though many buildings are modest and have been resided. Water power supported a gristmill, a sawmill, the Shattuck gun shop and the Porter-McLeod lathe works. These industries drew central and eastern European immigrants, who also worked on local farms growing tobacco, onions and dairy products. Tobacco barns and livestock barns remain beside many houses. The district also contains the Borden Baseline, a copper bolt set in a boulder in 1830 as a survey point used to map Massachusetts and beyond.","period_of_significance":null,"architect_builder":null,"architectural_style":"Greek Revival, Italianate, Queen Anne, Colonial Revival","criteria":[],"status_note":"Mix of residential, industrial and agricultural buildings in residential and commercial use; some houses altered with vinyl siding and replacement windows.","vacant_flag":null,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:13:03.602693-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/81/7953/63795381/content/electronic-records/rg-079/NPS_MA/02001188.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/02001188/f34edd625e-800.webp","url_1600":"https://nationalhistoricalregister.com/media/02001188/f34edd625e-1600.webp","licence":"CC BY-SA 3.0","author":"John Phelan","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Old_Mill_on_the_Falls,_Hatfield_MA.jpg\" rel=\"noopener\">John Phelan</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:Old_Mill_on_the_Falls,_Hatfield_MA.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/63795381","wikipedia":"https://en.wikipedia.org/wiki/Mill%E2%80%93Prospect_Street_Historic_District","wikidata":"https://www.wikidata.org/wiki/Q6858163"},"indexable":true,"url":"https://nationalhistoricalregister.com/massachusetts/hampshire-county/mill-prospect-street-historic-district-02001188/"}
