It is described as Rockland's finest example of Classical Revival commercial architecture and one of few surviving nineteenth and early twentieth century commercial buildings in the town. It is also linked to a prominent Boston architectural firm and to the businessman Alonzo W. Perry.","narrative":"Standing at the corner of Union and Park Streets in Rockland, this two-story commercial block was built in 1929 after fire destroyed the second of two earlier Phoenix buildings on the site. Boston architects Blackall, Clapp & Whittemore designed it with a cast-stone ashlar facade, green marble storefront bases, copper pilasters, and a parapet of vase balusters. Three shops occupy the ground floor and offices fill the second story, where original doors, trim and a pressed tin ceiling in one store survive. The building was erected for the real estate firm of Alonzo W. Perry, a former Rockland shoe manufacturer who became a Boston-based property owner. It was listed for its architecture and for its role in the town's commercial life. Few commercial buildings from the late nineteenth and early twentieth centuries remain in Rockland, and this one is notable for the variety of its cast-stone and metal ornament and for retaining most of its original detail.","period_of_significance":"1929-1939","architect_builder":"Blackall, Clapp & Whittemore","architectural_style":"Later 19th Century & 20th Century Revival: Neo-Classical (described in the text as Renaissance Revival / Classical Revival)","criteria":["A","C"],"status_note":"Still used for business and office purposes, with three storefronts on the first story and offices on the second; the nomination describes it as well preserved.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:13:01.228808-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/20/7965/63796520/content/electronic-records/rg-079/NPS_MA/89000220.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/89000220/e6db809a6f-800.webp","url_1600":"https://nationalhistoricalregister.com/media/89000220/e6db809a6f-1600.webp","licence":"CC BY 3.0","author":"John Phelan","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Phoenix_Building,_Rockland_MA.jpg\" rel=\"noopener\">John Phelan</a>, <a href=\"https://creativecommons.org/licenses/by/3.0\" rel=\"license noopener\">CC BY 3.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Phoenix_Building,_Rockland_MA.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/63796520","wikipedia":"https://en.wikipedia.org/wiki/Phoenix_Building_(Rockland,_Massachusetts)","wikidata":"https://www.wikidata.org/wiki/Q2088497"},"indexable":true,"url":"https://nationalhistoricalregister.com/massachusetts/plymouth-county/phoenix-building-89000220/"}
