It is also prominently sited on a small hill near Round Mountain with several related stone and wood-frame structures. It is part of the Norwegian settlement of Bosque County thematic group.","narrative":"Overlooking the Meridian Creek valley in Bosque County, Texas, this farm sits on a small hill about four and a half miles west of Clifton, near a pass between Round Mountain and Big Bee Rock. Its main building is a one-and-a-half-story limestone house with a five-bay south front, a central door under a curved segmental arch, and six-over-six double-hung windows. Stone chimneys rise at both gable ends. A one-story stone structure, possibly the original kitchen, was joined to the rear, giving the house a T-shaped plan, and a standing-seam metal roof covers the whole. A small stone outbuilding with a cellar is dug into the hillside, and two wood-frame barns stand nearby. Ole and Antonette Olson, who apparently arrived in the county in the 1850s, probably built the house in the 1860s; it was later sold to O. D. (Dan) Nelson. The farm was listed as a good example of the symmetrical stone house with a rear kitchen wing. It is unoccupied but in good condition.","period_of_significance":null,"architect_builder":"Ole and Antonette Olson (builders/original owners)","architectural_style":"Symmetrical stone-house type","criteria":[],"status_note":"Described as unoccupied but in good condition, retaining much of its historic integrity; present use listed as vacant, agriculture.","vacant_flag":true,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:54:19.337643-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/83/9683/40968383/content/electronic-records/rg-079/NPS_TX/83003116.pdf"},"photo":null,"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/40968383","wikipedia":null,"wikidata":"https://www.wikidata.org/wiki/Q110001668"},"indexable":true,"url":"https://nationalhistoricalregister.com/texas/bosque-county/olson-nelson-farm-83003116/"}
