Photographs of the historic Cathedral Building in downtown Oakland, California.

The Cathedral Building (originally named the Federal Realty Building), built in 1914, was the first Gothic Revival style skyscraper west of the Mississippi River, located in Oakland, California.

It is also called the “Wedding Cake” for its appearance, which resembles New York’s Flatiron Building. Its narrow, triangular form is a result of its location on Latham Square, where Telegraph Avenue branches off diagonally from Broadway. It was designed by architect Benjamin McDougall. In June 2015, the United Nations Foundation commissioned Bay Area street artist Zio Ziegler to create a mural on the Cathedral Building’s north-facing wall. The mural commemorates the signing of the United Nations Charter in San Francisco, California on June 26, 1945.
