It was built in 1928 to designs by architect Horace Trumbauer.","why_significant":"The nomination argues the building is a distinguished design by one of Philadelphia's foremost architects and that it is the principal Philadelphia example of period Art Deco among the high-rise spires built around Rittenhouse Square in the 1920s. It is also presented as the last phase of Trumbauer's career, where he combined Art Deco massing with Lombardic Romanesque detail. Its site has been architecturally significant since the 1840s.","narrative":"Rising 27 stories above a narrow 34 by 190 foot lot on the west side of Rittenhouse Square, the Chateau Crillon was completed in 1928 to designs by Horace Trumbauer. Its rough yellow brick walls are accented with limestone at the corners, setbacks and base openings, and the building steps back at the 17th and 24th floors before ending in a tall hipped roof that gives the building its name. Its Lombardic Romanesque detailing, including arched lintels, corbel-table cornices and spiralled corner columns, is applied to a tall, vertically organized mass. The nomination regards it as one of a group of high-rise towers that gathered around the square in the 1920s, and as the principal Philadelphia example of period Art Deco. It also marks the end of Trumbauer's career, when he moved from neo-baroque civic and mansion work to this later design. Stained glass transoms and wrought iron grilles survive at the ground floor, and the lobby opens upward rather than deeper into the narrow site.","period_of_significance":"1928","architect_builder":"Horace Trumbauer (architect)","architectural_style":"Art Deco with Lombardic Romanesque detail","criteria":["C"],"status_note":"Facade is described as largely unaltered apart from a modern shop at the base and corner column at 19th Street.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:29.386986-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/78002443.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/78002443/cd6556cdc1-800.webp","url_1600":"https://nationalhistoricalregister.com/media/78002443/cd6556cdc1-1600.webp","licence":"Public domain","author":"Smallbones","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Chateau_Crillon_2.JPG\" rel=\"noopener\">Smallbones</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Chateau_Crillon_2.JPG"},"district":{"nrhp_refnum":"87002203","name":"Center City West Commercial Historic District","url":"https://nationalhistoricalregister.com/districts/pennsylvania/center-city-west-commercial-historic-district-87002203/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71996938","wikipedia":"https://en.wikipedia.org/wiki/Chateau_Crillon_Apartment_House","wikidata":"https://www.wikidata.org/wiki/Q5087529"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/philadelphia/chateau-crillon-apartment-house-78002443/"}
