It was originally at A and First Streets and has since been moved twice, to its present site at 1046 Grove Way.","why_significant":"The nomination argues the church is an excellent, sophisticated example of the Greek Revival style under Criterion C. It is one of the earliest surviving churches in Alameda County and possibly the only Greek Revival church of its kind in the East Bay. It also retains a high degree of integrity despite being moved in 1947 and 2003.","narrative":"Built in 1867 for a congregation organized two years earlier, this small wooden church in Hayward, California, originally stood at A and First Streets and cost $3,200. Now called the Pioneer Chapel, it measures 68 by 36 feet and shows Greek Revival design in its symmetrical front, central entrance bay with pediment and pilasters, segmental arch windows, and an octagonal bell tower. It was the second Protestant church in the town, and the others from that era were later demolished or converted. The building was moved about a mile in 1947, when the bell tower was removed and a rear office and classroom addition was added, and again in 2003 by about 400 feet to Grove Way. The addition aside, the exterior keeps its original character and still serves regular worship. It was listed as an excellent example of Greek Revival architecture and as one of the earliest surviving churches in Alameda County.","period_of_significance":"1867","architect_builder":null,"architectural_style":"Mid-Nineteenth Century/Greek Revival","criteria":["C"],"status_note":"Still used on Sundays and other days by two church groups and the Eden United Church of Christ, which owns it; moved to a reinforced concrete foundation in 2003.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:54:29.779731-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_CA/07000788.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/07000788/d06f2814a6-800.webp","url_1600":"https://nationalhistoricalregister.com/media/07000788/d06f2814a6-1600.webp","licence":"CC BY-SA 3.0","author":"Sanfranman59","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Eden_Congregational_Church_(Hayward,_CA).JPG\" rel=\"noopener\">Sanfranman59</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:Eden_Congregational_Church_(Hayward,_CA).JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/123858208","wikipedia":"https://en.wikipedia.org/wiki/Eden_Congregational_Church","wikidata":"https://www.wikidata.org/wiki/Q5336834"},"indexable":true,"url":"https://nationalhistoricalregister.com/california/alameda-county/eden-congregational-church-07000788/"}
