It is also significant for humanitarian reasons, because Caroline Mark left her estate to build and permanently maintain a free home for needy elderly women. The building retains its original character, fabric and features.","narrative":"Built in 1906 on a 4.91-acre tract in Mount Carroll, the Caroline Mark Home is a two-story brick building, 33 feet wide and 134 feet long, that has housed needy elderly women since its first residents arrived in 1908. Caroline Wade Mark came to Mount Carroll in 1836 and married James Mark, a landowner and bank president, in 1843. Having seen many older women left penniless, she left most of her estate to build the home and to pay for its upkeep and the residents' needs. The building has reinforced concrete floors and roof, limestone trim, a Huntington Shingle Tile hipped roof, oak interior woodwork, a cast iron stair with Tennessee marble treads and ceramic mosaic floors. Its masonry and detailing reflect the arts and crafts movement. A smoke house, ice house, pumphouse and caretaker's house date from the same period. Alterations are limited to a fire escape, an access ramp and revised gutters.","period_of_significance":"1906","architect_builder":"Berkeley Brandt","architectural_style":"Arts and crafts movement","criteria":[],"status_note":"Occupied and in good condition; it continues to house elderly women, as it has since its first occupants arrived in 1908.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:55:35.470446-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/72/8917/28891772/content/electronic-records/rg-079/NPS_IL/83000303.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/83000303/512892d680-800.webp","url_1600":"https://nationalhistoricalregister.com/media/83000303/512892d680-1600.webp","licence":"Public domain","author":"Nyttend","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Caroline_Mark_House.jpg\" rel=\"noopener\">Nyttend</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Caroline_Mark_House.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/28891772","wikipedia":"https://en.wikipedia.org/wiki/Caroline_Mark_Home","wikidata":"https://www.wikidata.org/wiki/Q20711783"},"indexable":true,"url":"https://nationalhistoricalregister.com/illinois/carroll-county/mark-caroline-house-83000303/"}
