The Hollywood Knickerbocker Hotel:

View of the Hollywood Knickerbocker Apartment Hotel, located at 1714 Ivar Avenue. In 1923 E. M. Frasier built this 11-story hotel in Spanish Colonial style, which catered to Hollywood's film industry and was home to many stars throughout the years. This historic building began life as a luxury apartment building that was at the heart of Hollywood back in the 1920s, before becoming a hotel later in its history; its slogan was "Your home for a year or a day". It's been linked with tragic deaths and because of this, it is considered haunted by some. Some unfortunate occurrences: D.W. Griffith died of a stroke on July 21, 1948 under the crystal chandelier of the lobby; a costume designer named Irene Gibbons jumped to her death from a hotel window; William Frawley, who lived at the hotel for decades, died of a heart attack on the sidewalk in front of the Knickerbocker. Other stars that frequented the hotel with better luck were: Rudolph Valentino, Elvis Presley, Marilyn Monroe and Joe DiMaggio, Frank Sinatra, Lana Turner, Mae West, and Cecil B. DeMille among many, many others. In 1970 a renovation project converted the hotel into housing for senior citizens and it continues in this capacity today.
