It was built for Conrad N. Hilton and was his first highrise in Texas and the first building to bear his name. It marks the start of the second phase of his hotel career.","narrative":"Rising fourteen stories on the highest point in downtown Dallas, this hotel at Main and Harwood streets was completed in 1925 for Conrad N. Hilton. It has a horseshoe plan with two massive towers joined by an arched entrance and an ornate bridge at the tenth level. Terra-cotta, granite, cast-iron and wrought-iron details recall Beaux Arts design. Lang and Witchell, a leading Dallas firm, designed it, and McKenzie Construction built it for about $1,360,000. It was Hilton's first highrise in Texas and the first building to carry his name, and it began a new phase in the career of the man who became a leading hotelier. It later operated as the White-Plaza and then the Plaza. The 1950s windows, new lighting and wall coverings, and a reduced room count altered the interior and some openings, but the exterior ornament remains largely intact. When documented in 1985 the hotel was closed for restoration and renovation.","period_of_significance":"1900- (specific date 1925)","architect_builder":"McKenzie Construction of Dallas and San Antonio / Lang and Witchell","architectural_style":"Beaux Arts influence","criteria":["A","B","C"],"status_note":"Closed in February 1985 for a projected nine-month exterior restoration and interior renovation; the form lists the property as vacant and unoccupied.","vacant_flag":true,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:54:21.289937-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/59/9716/40971659/content/electronic-records/rg-079/NPS_TX/85003092.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/85003092/0a4315dc78-800.webp","url_1600":"https://nationalhistoricalregister.com/media/85003092/0a4315dc78-1600.webp","licence":"CC BY-SA 3.0","author":"M.I.B. at English Wikipedia","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Hotel_Indigo_Downtown_Dallas_01.jpg\" rel=\"noopener\">M.I.B. at English Wikipedia</a>, <a href=\"https://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:Hotel_Indigo_Downtown_Dallas_01.jpg"},"district":{"nrhp_refnum":"04000894","name":"Dallas Downtown Historic District (Additional Documentation)","url":"https://nationalhistoricalregister.com/districts/texas/dallas-downtown-historic-district-additional-documentation-04000894/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/40971659","wikipedia":"https://en.wikipedia.org/wiki/Hilton_Hotel_(Dallas,_Texas)","wikidata":"https://www.wikidata.org/wiki/Q1158001"},"indexable":true,"url":"https://nationalhistoricalregister.com/texas/dallas-county/hilton-hotel-85003092/"}
