On May 27, 1977,
the Mayor and Aldermen decided to set up the ‘Work Staff for Public Lighting in the Inner City’. In the years that followed, the Staff ensured that public lighting was installed which adapted to the atmosphere of the city center.
Engineer A.D.M. van Tilburg, head of Public Lighting in Utrecht from 1970 to 1998, was the initiator and driving force in the Working Group.
One of the results has been that the Utrecht variety of light sources has been expanded with the Berlin Gamma lantern.
Initiated by van Tilburg, the Gamma lanterns were placed in the park next to the Sonnenborgh observatory in the autumn of 1996.
