Clarke in Chicago. It now stands at 1827 South Indiana Avenue after being moved twice, in 1872 and 1977.","why_significant":"It qualified under Criterion C as a Greek Revival style house. It meets the criteria consideration for moved properties because its new setting matches its historic one in acreage, setback and east-facing orientation. Much of the original timber frame, siding and interior layout survives.","narrative":"Begun in 1836 by Henry B. Clarke, this thirteen-room Greek Revival house is a two-story timber-frame dwelling built of rough-hewn oak beams with mortise and tenon joints. It was first built near 16th Street and Michigan Avenue, moved in 1872 to Wabash Avenue, and moved again in 1977 to 1827 South Indiana Avenue, about one and one-half blocks from its original site. The house sits in a five-acre public park, matching the acreage associated with the property in 1860, and its setback and east-facing orientation echo the original setting. Interior moldings show both Federal and Greek Revival influence because Clarke's finances suffered after 1837 and two parlors were finished after 1849. The City of Chicago restored the house in 1980, rebuilding the four-column portico from a circa 1855 daguerreotype. Its significance rests on its architecture as a Greek Revival house, with original framing, siding and room layout still intact.","period_of_significance":null,"architect_builder":null,"architectural_style":"Greek Revival","criteria":["C"],"status_note":"Restored by the City of Chicago in 1980 and operated as a museum on a five-acre public park; the portico was restored from a circa 1855 daguerreotype.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:55:35.741103-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/44/8923/28892344/content/electronic-records/rg-079/NPS_IL/71000290.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/71000290/c58b61c201-800.webp","url_1600":"https://nationalhistoricalregister.com/media/71000290/c58b61c201-1600.webp","licence":"CC BY-SA 3.0","author":"Original uploader was Prairieavenue at en.wikipedia","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Clarke_House_new.jpg\" rel=\"noopener\">Original uploader was Prairieavenue at en.wikipedia</a>, <a href=\"http://creativecommons.org/licenses/by-sa/3.0/\" rel=\"license noopener\">CC BY-SA 3.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Clarke_House_new.jpg"},"district":{"nrhp_refnum":"72000452","name":"Prairie Avenue District","url":"https://nationalhistoricalregister.com/districts/illinois/prairie-avenue-district-72000452/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/28892344","wikipedia":"https://en.wikipedia.org/wiki/Henry_B._Clarke_House","wikidata":"https://www.wikidata.org/wiki/Q3132596"},"indexable":true,"url":"https://nationalhistoricalregister.com/illinois/cook-county/clarke-henry-b-house-71000290/"}
