Keaton had served on the board of the Los Angeles Conservancy and as a trustee of the National Trust for Historic Preservation.<\/p>\n
Her activism included efforts to save the Ennis House<\/a>, an iconic 1920s residence in the Hollywood Hills that was designed by the famed architect Frank Lloyd Wright.<\/p>\n The Northridge earthquake in 1994 and heavy rains a decade later caused significant damage. The National Trust for Historic Preservation placed the house on its 2005 list of\u00a0America\u2019s 11 Most Endangered Historic Places.<\/p>\n It\u00a0was partially restored by the nonprofit Ennis House Foundation, then was purchased and fully restored in 2011. According to the Frank Lloyd Wright Building Conservancy<\/a>, Keaton called on the Hollywood community to help save the house, which has been featured in numerous films, and eventually joined the Ennis House Foundation board.<\/p>\n Jim Steinfeldt\/Michael Ochs Archives\/Getty Images<\/p>\n Keaton also fought to preserve the Century Plaza Hotel, which was built in the 1960s and also placed on the 11 Most Endangered Historic Places list in 2009.<\/p>\n The owners at the time proposed razing the hotel and replacing it with a mixed-use development, which Keaton said \u201cis part of an uninspired assault on 1960s large-scale architecture in Los Angeles<\/a>.\u201d<\/p>\n But the city approved a project that preserved the hotel as the centerpiece. Rehabilitation began in 2016, and the hotel reopened in 2021, according to the Los Angeles Conservancy<\/a>. <\/p>\n Efforts to save the 1920-era Ambassador Hotel, however, weren\u2019t successful. An early symbol of the city\u2019s development and the site of Robert F. Kennedy\u2019s assassination, the hotel was demolished in 2005 to make way for the construction of a school.<\/p>\n![\"\"](\"https:\/\/www.europesays.com\/us\/wp-content\/uploads\/2025\/10\/GettyImages-158956732-e1760225936837.jpg\"\/)
