South San Francisco Hillside Sign

The South San Francisco Hillside Sign is a large white concrete sign mounted on a hillside overlooking the city. The letters are visible from great distances and prominently shape the city's appearance.

The sign was initiated in 1923 by the Chamber of Commerce and later replaced with larger concrete letters in 1929 to promote industrial growth. This expansion reflected the city's early economic ambitions and development.

The sign represents the city's identity and is seen by residents as a landmark that defines their community. Visitors recognize it as a symbol that makes the place memorable and distinct.

Sign Hill Park offers hiking trails that lead up to the letters and allow close-up views of the sign. Best access is through parking areas at the base of the hill.

The letters use a special optical technique that makes them appear the same size from different distances and angles. This creates a uniform look despite the letters having different actual heights.
