Columbus Tower, San Francisco

Columbus Tower, San Francisco

The Columbus Tower—also known as the Sentinel Building—has seen more drama than most Hollywood sets. It was built between 1905 and 1907 under the watchful eye (and wallet) of lawyer-politician Abe Reuf, who felt that San Francisco needed a showpiece. The gleaming project barely got off the ground, though, when the 1906 earthquake struck. The quake and the fires that followed reduced it to a lonely steel skeleton.

But San Francisco doesn’t stay down for long. Undeterred, Reuf rebuilt the tower in 1907, wrapping it in gleaming copper and setting up his office at the very top—until karma called... Just two years later, Reuf was convicted of bribery and sentenced to 14 years in prison. While he served time, the building’s copper cladding quietly aged into that now-iconic green patina.

Over the decades, the building’s story only got juicier. Legend has it that the first Caesar salad was tossed right here at Caesar’s restaurant, located inside the tower, until Prohibition shut it down in 1919. The building’s creative streak returned in the 1960s, when folk group The Kingston Trio turned the basement into their recording studio.

By the 1970s, the tower looked tired—until filmmaker Francis Ford Coppola stepped in like a cinematic savior. He bought it, restored its vintage glow, and installed his American Zoetrope studio. Today, as San Francisco Landmark No. 33, the Columbus Tower stands proud—part movie history, part culinary myth, and part copper-clad survivor—presently serving Napa Valley wine instead of scandal at the charming Zoetrope Café on the ground floor...
