For the lighting system created by Acea SpA thanks to an agreement with Mibact and Gesesa, with the placet of the Superintendence and in agreement with the Municipality, it was decided to light both the exterior (top of the crown, pillars and apses) of the architectural structure of the Theatre and the interior (auditorium and stalls) with sustainability (the overall power is in fact 3,200 W), in two different colours (white and yellow-gold), which made it possible to highlight the differences in the materials the structure is made of.
