Mt. Davidson is the city's tallest hill, at 938 feet above sea level, and is crowned by a controversial 100-foot cross. The nearby Twin Peaks are nearly as high at 910 feet. These hills were considered to be among San Francisco 's original seven hills, copied from the seven hills of Rome . As the city has grown and populated pretty much every peak, it has named at least 43 hills, including two in Diamond Heights : Red Rock Hill and Gold Mine Hill. No matter which peak you pick, the postcard views will remind you of why you wanted to buy a home in San Francisco (notwithstanding the behemoth Sutro Tower on nearby Mount Sutro ). Hillside properties on Twin Peaks and Mount Davidson are typically nice, older, detached homes. The Diamond Heights area was developed in the late 1960s and is a mix of single family, condos, townhomes and apartment buildings.
