This entry covers the boundary increase to the existing Mexican War Streets Historic District, adding areas to the north and east.","why_significant":"The nomination argues the boundary increase areas are significant as a cohesive concentration of residential buildings in a variety of architectural styles that reflect the architectural tastes of the community over the period of significance. The area was built up from 1848 to about 1930 and shares the historic background and visual character of the existing district.","narrative":"Closely built brick and stone houses on a narrow urban grid north of the Allegheny River mark this residential district on Pittsburgh's North Side. The streets were platted in 1848 in the Buena Vista Extension, named for generals and battles of the Mexican War, and most houses were built between then and about 1930. The boundary increase adds 317 buildings, 303 of them houses or apartment buildings, along Monterey, Armandale, Sherman, Veto and Arch Streets. Their architecture spans Greek Revival, Italianate, Second Empire, Queen Anne and Classical Revival styles. The district is listed for its concentration of these styles, which together show the taste of the community across the nineteenth century. Roughly three-quarters of the buildings are brick or stone, and about 15 percent have mansard roofs. Revitalization efforts beginning in the late 1960s helped preserve the older core.","period_of_significance":"1848 - c. 1930","architect_builder":null,"architectural_style":"Greek Revival, Italianate, Second Empire, Romanesque, Queen Anne, Classical Revival","criteria":["C"],"status_note":"The boundary increase area includes empty lots along Federal Street where demolition occurred for redevelopment, and the district was subject to renovation and revitalization from the late 1960s.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:10:27.473513-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/08000845.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/08000845/2b5885d999-800.webp","url_1600":"https://nationalhistoricalregister.com/media/08000845/2b5885d999-1600.webp","licence":"CC BY-SA 3.0","author":"Ainulindale","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Warstrs.JPG\" rel=\"noopener\">Ainulindale</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:Warstrs.JPG"},"district":{"nrhp_refnum":"75001612","name":"Mexican War Streets Historic District,","url":"https://nationalhistoricalregister.com/districts/pennsylvania/mexican-war-streets-historic-district-75001612/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71997656","wikipedia":"https://en.wikipedia.org/wiki/Mexican_War_Streets","wikidata":"https://www.wikidata.org/wiki/Q6825998"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/allegheny-county/mexican-war-streets-historic-district-boundary-increase-08000845/"}
