The house was completed around 1872-1873 and is also known as Stonehenge.","why_significant":"The farmstead is argued to be significant under Criterion A for its link to the Lake Erie islands wine-growing industry, as a typical small family vineyard farm. It is also significant under Criterion C as an example of vernacular Upright and Wing architecture built of native grout and dolomite, a rare material on the island.","narrative":"This stone farmhouse on Langrum Road, South Bass Island, was completed around 1872-1873 on a 15-acre farm that once held a vineyard, orchard and wine press house. The L-shaped Upright and Wing house is built of grout and Put-in-Bay dolomite laid as uncoursed rubble, a material found on only a few Lake Erie islands. A stone press house, now a cottage, stands nearby, along with a later barn that does not contribute to the property's significance. The farm reflects the small family wineries that made the Lake Erie islands a major wine-producing region from the 1860s into the early 1900s. James W. Foster, a carpenter and boat builder, acquired the land and likely built the press house before his death in 1871. The house was possibly built by William and Frank Wild, though other sources name different builders. Later owners included the Gram family and a Cleveland orthodontist. The buildings have changed little since the 1870s and are open for tours.","period_of_significance":"1870 - 1935","architect_builder":"William Wild ?","architectural_style":"Mid-19th Century; Upright and Wing (vernacular)","criteria":["A","C"],"status_note":"Open to public tours as a restoration in progress project; the press house has been converted to a cottage.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:53:14.794266-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_OH/92000175.pdf"},"photo":null,"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71990833","wikipedia":null,"wikidata":null},"indexable":true,"url":"https://nationalhistoricalregister.com/ohio/ottawa-county/foster-gram-house-92000175/"}
