Greenwich, London

Client: National Maritime Museum
Team: Artists Peter Fink + Anne Bean

The Royal Observatory Greenwich is the home of Greenwich Mean Time and the Prime Meridian of the World.

In 1992 we have conceived of the idea of a laser originating at the Greenwich Observatory

with idea of making visible the invisible as a poetic presence over London. By making this important Meridian line visible we have revealed it crosses at high tide the Thames three times within short distance from the observatory. The installation has involved extensive negotiations with the Civil Aviation Authority, Port of London and the emergency and security

Organizations. Currently the laser is longest functioning permanent laser installation in Europe and is on safely every night for over 20 years.
