It shows only that the district was created by statute to be administered with the national park, and that its listing followed a delegation of authority to the National Park Service Director.","narrative":"Lowell Historic Preservation District is an area of Lowell, Massachusetts, set beside Lowell National Historical Park. Congress established it in 1978 as part of the law creating the park, and its boundaries follow a map dated March 1978 that was later revised in 1980, 1987 and 1989. Under the statute, the Secretary of the Interior and a commission were to administer the district. Its listing in the National Register came administratively on January 19, 2001, when the Secretary delegated authority over the district to the Director of the National Park Service. An Interior Department attorney concluded that the district was thereafter administered as part of the park for limited purposes. The file contains mostly correspondence, legal text and boundary maps, and no building descriptions, architects, dates of construction or criteria. It also records that questions about the district's status, including its eligibility for investment tax credits, were raised by a preservation consultant in 2002.","period_of_significance":null,"architect_builder":null,"architectural_style":null,"criteria":[],"status_note":null,"vacant_flag":null,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:13:04.180173-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/82/7961/63796182/content/electronic-records/rg-079/NPS_MA/03000170.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/03000170/5733b6b5dd-800.webp","url_1600":"https://nationalhistoricalregister.com/media/03000170/5733b6b5dd-1600.webp","licence":"CC BY-SA 3.0","author":"The original uploader was Decumanus at English Wikipedia.","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Lowell_Boott_Cotton_Mill.jpg\" rel=\"noopener\">The original uploader was Decumanus 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:Lowell_Boott_Cotton_Mill.jpg"},"district":{"nrhp_refnum":"76001972","name":"Lowell Locks and Canals Historic District","url":"https://nationalhistoricalregister.com/districts/massachusetts/lowell-locks-and-canals-historic-district-76001972/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/63796182","wikipedia":"https://en.wikipedia.org/wiki/Lowell_Historic_Preservation_District","wikidata":"https://www.wikidata.org/wiki/Q6693220"},"indexable":true,"url":"https://nationalhistoricalregister.com/massachusetts/middlesex-county/lowell-historic-preservation-district-03000170/"}
