The main mansion house was completed in 1912 and designed by Wilson Eyre, with most other buildings dating from about 1912 to 1922.","why_significant":"The nomination argues that Allgates is a fine example of an early twentieth-century estate and a representative work of Wilson Eyre's domestic architecture, the only surviving Eyre work in Haverford Township. It also cites the formal gardens, which Mrs. Lloyd, wife of the original owner, was known for her horticultural knowledge in, and the Federal School (1797-1872) and Frog Tavern (c. 1731) incorporated into the complex.","narrative":"Allgates is a 26.6-acre estate in Haverford, Delaware County, Pennsylvania, containing nineteen structures and formal gardens bounded by Darby and Coopertown Roads. Its mansion, finished in 1912, is built of New Jersey sandstone with a triple-arched portico and an irregular plan of gables, and was designed by the Philadelphia architect Wilson Eyre. Most of the other buildings, including a stable, garage, and gazebos, date from about 1912 to 1922, while older structures are incorporated into the complex: a farmhouse of about 1850, the Frog Tavern from about 1731, and the Federal School, which operated from 1797 to 1872 and is the earliest remaining school in Haverford Township. The estate is valued for its architecture, its gardens, and its role in the work of Eyre, who regarded it as the only surviving example of his work in the township. The gardens are associated with Mary Helen Windgate Lloyd, a horticulturist and director of the Garden Club of America.","period_of_significance":"1731, 1797, 1850, 1912","architect_builder":"Wilson Eyre (architect)","architectural_style":null,"criteria":[],"status_note":"Excellent condition is checked on the form.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:31.099525-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/79002222.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/79002222/bbc8d80a03-800.webp","url_1600":"https://nationalhistoricalregister.com/media/79002222/bbc8d80a03-1600.webp","licence":"Public domain","author":"User:Smallbones on English Wikipedia.","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Allgates.jpg\" rel=\"noopener\">User:Smallbones on English Wikipedia.</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Allgates.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71995845","wikipedia":"https://en.wikipedia.org/wiki/Allgates","wikidata":"https://www.wikidata.org/wiki/Q4732239"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/delaware-county/allgates-79002222/"}
