Columbus Tower, Architectural structure in United States.
The Columbus Tower, also known as the Sentinel Building is located in San Francisco and has an unmistakable presence in the North Beach neighborhood.
Columbus Tower was completed in 1907, just after the San Francisco earthquake and has been a symbol of resilience ever since.
Over the years, the distinctive green copper-clad building has housed many cultural institutions including the Kingston Trio and Francis Ford Coppola's American Zoetrope film studio.
