A stop on San Francisco, District by District, a free self-guided tour.

The copper-green flatiron at Columbus Avenue and Kearny Street was going up when the 1906 earthquake struck, and it was finished in 1907, one of the first new buildings in the burned city. Its narrow wedge follows Columbus Avenue, a diagonal cut through the street grid in the 1870s as a shortcut from downtown to North Beach.

Its tenants read like a short history of the city. The top floor first held the offices of Abe Ruef, the political boss later convicted in the graft trials that followed the fire. In the early 1950s the hungry i nightclub got its start in the basement. The folk group the Kingston Trio bought the building in the late 1950s, and in 1972 filmmaker Francis Ford Coppola's American Zoetrope moved in; he restored its original name, the Sentinel Building.

Look up at the copper skin, turned green by a century of salt air.
