Alex Giuliani Plaza is a park surrounding a vacant building in downtown Hayward, California.
A circle-in-square design element on the building's facade was used to create the current city logo.
The current Hayward City Hall is located at 777 B Street, three blocks away from Giuliani Plaza.
A trace from the Hayward Fault runs directly under the old City Hall building.
The building was abandoned due to structural damage caused by aseismic creep.
