Its boxwood garden and plantings are described as one of the few surviving mid-19th-century gardens in the state. The house, its outbuildings and the garden together form a symmetrical, classically organized landscape.","narrative":"Bonar Hall is a two-story brick house on Dixie Avenue in Madison, Georgia, built in 1832 by John Byne Walker as the center of his large Morgan County cotton plantation. The house sits at the middle of a symmetrical layout, with a kitchen, orangery, pergola and privies arranged around it. Its exterior is plantation-made red brick, and the interior follows a plain Greek plan with a central hall and two rooms on each side. A lacy two-story Victorian veranda was added in the 1880s, replacing the original Doric portico. The estate has shrunk to about 100 acres and is a private residence. The nomination highlights the boxwood garden, planted by Eliza Fannin Walker, with cork oaks, mock oranges, yews, magnolias and other specimen trees, many from the original planting. It describes the property as one of the few surviving mid-19th-century gardens in Georgia and an important architectural landmark in Madison.","period_of_significance":"19th Century (specific dates 1832, c. 1880s)","architect_builder":"John Byne Walker (builder/original owner)","architectural_style":"Late Georgian / Greek Revival, with Victorian verandas added in the 1880s","criteria":[],"status_note":"Used as a private residence and occupied; the owner planned to remove the Victorian verandas and restore the original Doric portico and balustraded parapet.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:55:40.666589-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_GA/72000388.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/72000388/af43a596b7-800.webp","url_1600":"https://nationalhistoricalregister.com/media/72000388/af43a596b7-1600.webp","licence":"CC BY-SA 4.0","author":"Cynthia Jennings","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Front_View_of_Bonar_Hall.jpg\" rel=\"noopener\">Cynthia Jennings</a>, <a href=\"https://creativecommons.org/licenses/by-sa/4.0\" rel=\"license noopener\">CC BY-SA 4.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Front_View_of_Bonar_Hall.jpg"},"district":{"nrhp_refnum":"74000696","name":"Madison Historic District","url":"https://nationalhistoricalregister.com/districts/georgia/madison-historic-district-74000696/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/93209027","wikipedia":"https://en.wikipedia.org/wiki/Bonar_Hall","wikidata":"https://www.wikidata.org/wiki/Q4941187"},"indexable":true,"url":"https://nationalhistoricalregister.com/georgia/morgan-county/bonar-hall-72000388/"}
