California Info-Visual Siren Archive [CISA]

"The Official Siren Archive for the State of California..."

Hello there! Welcome to California Info-Visual Siren Archive. Our mission here is to document the many remaining siren vessels standing throughout the Golden State of California.

The four primary objectives of CISA include:

• To provide visual documentation of each siren within the Golden State
• To exhibit information regarding historical purposes of each siren system
• To educate the public on the usefulness of such alerting devices
• To cultivate the siren hunting hobby

Below you will find the main directory of the state siren archive:
