The old tower no longer exists, as it was demolished in the late '90s, but it was a true urban icon not so much because of its 21 metre height but for the unusual effects created by light irradiated toward the city.
The lighting system was controlled by 2 computers which modified the intensity and direction of various light sources on the basis of natural light, weather conditions, wind speed and external noise.
Toyo Ito's intention was above all to keep the building's relationship with the city alive, even at night, so that the building would not "switch off" but continue to interact with its surroundings even in the absence of natural light.
This was a very innovative idea at that time, in line with the new way of viewing light not as a merely functional element but as an integral part of architecture and design, an expressive, characterising element with great potential.
