San Francisco, CA Photo - Columbus Tower, San Francisco, California

Columbus Tower, also known as the Sentinel Building is a mixed-used building in San Francisco, California completed in 1907. The distinctive copper-green Flatiron style structure is bounded by Columbus Avenue, Kearny Street and Jackson Street, straddling the North Beach-, Chinatown-, and Financial-districts of the city. It is designated landmark number 33. By the early 1970s the building was falling gradually into a state of mild disrepair. The film director Francis Ford Coppola chose then to purchase the building, and renovate it into the building that can be seen today. Coppola then set up his own business in the building, and remains there to this day.
