It sits on the north side of the west end of Main Street.","why_significant":"The nomination argues the block is significant for its link to the gradual conversion of west Main Street into a commercial area in the early 20th century. It is also valued as a well preserved, detailed early 20th century commercial block. It meets criteria A and C.","narrative":"Built around 1910, this one-story wood-frame commercial block stands on the north side of Main Street at the west end of Hyannis's commercial area. It is sheathed in wood shingles and capped by a gable roof. A full shed dormer across the front slope holds seven evenly spaced windows with 6/1 sash and provides second-story storage space. The storefronts keep their original layout, with narrow two-light transoms and paired recessed entries, and scalloped valances trim both the main roof and the dormer. No architect is known, and no major alterations were recorded. The building was listed because it typifies west Main Street's gradual shift from residential to commercial use in the early 20th century. Although plainly commercial, its scale and materials relate to the earlier houses nearby. Intact older blocks like this one add to Hyannis's character as a summer resort and reflect how it developed around the turn of the century. It was recorded as retaining integrity and was found significant under criteria A and C.","period_of_significance":null,"architect_builder":null,"architectural_style":"Early 20th century commercial","criteria":["A","C"],"status_note":"Recorded in 1986 as in good condition, with no major alterations and used commercially.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:13:01.67231-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/31/7891/63789131/content/electronic-records/rg-079/NPS_MA/87000287.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/87000287/c49528ec06-800.webp","url_1600":"https://nationalhistoricalregister.com/media/87000287/c49528ec06-1600.webp","licence":"CC BY-SA 2.0","author":"Thomas Kelley from Boston, MA","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Building_at_606_Main_Street.jpg\" rel=\"noopener\">Thomas Kelley from Boston, MA</a>, <a href=\"https://creativecommons.org/licenses/by-sa/2.0\" rel=\"license noopener\">CC BY-SA 2.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Building_at_606_Main_Street.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/63789131","wikipedia":"https://en.wikipedia.org/wiki/Building_at_606_Main_Street","wikidata":"https://www.wikidata.org/wiki/Q4986578"},"indexable":true,"url":"https://nationalhistoricalregister.com/massachusetts/barnstable-county/building-at-606-main-street-87000287/"}
