Public Telephone is an interactive sound installation which allows people to leave and retrieve audio messages in designated locations throughout the city of Gothenburg.

Implemented using modified rotary telephones, users dial a number to leave a message or browse through previously recorded messages using a three digit-code.

Each three-digit code corresponds to a specific location within the city and is indicated on the map. Finally, the most recent recorded messages can be heard remotely via live broadcasting over the internet. The result is a city-wide "audio guestbook" which may reveal unexpected information about a certain location, time or space.

Public Telephone encourages city-dwellers to re-create the primitive tradition of the oral resonate world of sound via telephones. Messages may consist of spoken word, story-telling, music or other forms of oral expression . Once combined, these "audio-vignettes" will contribute to a public sound mosaic and may even help us navigate though the city as expressed in sound.
