City of Light 2015 event 

In 2015, UNESCO celebrated the Year of Light  and since then, the Global Day of Light  has been celebrated on the 16th of May. 

The City of Light event was one of the official events of the UNESCO “International Year of Light” — theme year. Therefore, the light event was also more wide-ranging as well as more international than in the previous years. The programme included almost over 40 different installations or ancillary events, including the Year of Light celebration seminar and Church Park, which was packed full by the award-winning Ave Fenix fire-puppet theatre and the fire-circus performance. 
 
The event had nearly 50,000 visitors. The event was made possible by the financial support of 17 operators.
