Telegraph Hill World famous Coit Tower rests atop Telegraph Hill, a small, hilly, tree-lined district located in the upper northeast section of San Francisco, just to the south of Fisherman?s Wharf. Originally known as Loma Alta ("High Hill"), Telegraph Hill got its current moniker circa 1849, when a semaphore was built at the top of the hill to indicate the nature of the ships entering San Francisco. In October 1850, a ship entering the Golden Gate signaled to the semaphore the news of California?s admittance as the 31st state. Mostly comprised of upscale residences today, Telegraph Hill was a popular destination for poets and intellectuals in the early 20th century. Besides Coit Tower, the neighborhood is known for its gardens along Filbert Street, as well as the flock of feral parrots immortalized in the 2005 documentary The Parrots of Telegraph Hill. Other famous films featuring this famous hill include Dark Passage, Vertigo, Guess Who?s Coming to Dinner, The Enforcer and The House on Telegraph Hill.
