Look up in admiration at the gleaming verdigris copper facade of Columbus Tower, also celebrated worldwide as the Sentinel Building. Perched boldly at the triangular junction where Columbus Avenue, Kearny Street, and Pacific Avenue intersect, this eight-story flatiron masterpiece was commissioned in 1905 by notorious political boss Abe Ruef. Construction was partially underway when the catastrophic earthquake of April 18, 1906 struck, but the resilient steel frame survived the shaking and the building was triumphantly completed in 1907, heralding the rapid rebirth of San Francisco.

In 1972, visionary Oscar-winning film director Francis Ford Coppola purchased the historic flatiron to serve as the creative headquarters for American Zoetrope studios. Beneath this distinctive copper cupola, Coppola and his brilliant team edited cinematic milestones including The Godfather Part II, Apocalypse Now, and The Conversation. The basement and lower floors house the charming Cafe Zoetrope, where diners savor wine and Italian fare surrounded by vintage movie posters, Oscars, and film scripts.

Examine the intricate copper ornamentation decorating the top story and domed roof; natural oxidation over more than a century has coated the metal in its distinctive, radiant sea-green patina. In 1970, the building was officially designated San Francisco City Landmark number thirty-three, protecting it forever from demolition. Generations of writers, artists, and independent thinkers have drawn creative energy from this very setting, cementing San Francisco's international reputation as a haven of intellectual freedom and community solidarity.
