Sunnylands, the former Annenberg Estate, located in Rancho Mirage, California, is a 200-acre (0.81 km²) estate currently run by The Annenberg Foundation Trust at Sunnylands, a not-for-profit organization and Annenberg family trust. The property was owned by Walter and Leonore Annenberg until 2009 and had been used as a winter retreat by the couple from 1966, when the house was completed. The property is "rich with historical significance," according to the city of Rancho Mirage, which declared Sunnylands an historic site in 1990. Located at Frank Sinatra and Bob Hope Drives, the property has been the vacation site of numerous celebrities and public officials.
