It was built in 1859 in three sections, with a later addition in 1925.","why_significant":"The nomination argues the house is the prototype of the country mansions built along the Pennsylvania Railroad Main Line from 1880 to 1920, and that it is both the first and the last remaining example of the Italian Revival in Radnor Township. It is also described as a rare survival among later eclectic architecture in the western Philadelphia suburbs. Its grounds are laid out in the English Romantic tradition.","narrative":"Built in 1859 on a 48-acre tract in Radnor Township by the builder Michael Erickson, this Italianate villa was among the earliest true country houses erected by a summer resident in the township, rather than a farmhouse enlarged for that purpose. The stucco-over-stone main section is three stories high and three bays wide, with symmetrical wing projections, a low hipped roof and a central door. Later additions followed in the late nineteenth century and in 1925, when George Howe designed an addition to the projecting wing and garden walls in 1928. The house is regarded as a prototype for the Main Line country mansions built along the Pennsylvania Railroad between 1880 and 1920. It is also considered the first and last surviving example of the Italian Revival style in Radnor Township, and its grounds follow the English Romantic tradition with close attention to trees.","period_of_significance":"1859","architect_builder":"Michael Erickson (builder); George Howe (architect of 1925 addition and 1928 garden walls)","architectural_style":"Italianate villa","criteria":["C"],"status_note":null,"vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:30.882737-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/77001163.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/77001163/d84960b975-800.webp","url_1600":"https://nationalhistoricalregister.com/media/77001163/d84960b975-1600.webp","licence":"Public domain","author":"User:Smallbones on English Wikipedia.","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Glenays.JPG\" rel=\"noopener\">User:Smallbones on English Wikipedia.</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Glenays.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71994821","wikipedia":"https://en.wikipedia.org/wiki/Glenays","wikidata":"https://www.wikidata.org/wiki/Q5568155"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/delaware-county/glenays-77001163/"}
