Between the archaeological site and the contemporary stage: an example of acoustic and lighting retrofit with multifunctional purpose in the ancient theatre of Syracuse

A research conducted on the contemporary use of ancient theatres is presented, focusing on sustainable solutions for passive acoustics and artificial lighting devices. The case study is the theatre of Syracuse, well known as archaeological tourist attraction and as traditional stage for theatrical events. A retrofit was suggested to avoid the use of loudspeakers in the theatre during representations, through the selection of the best performing orchestra shells. For the lighting part, the study focused on the theatre as archaeological site, improving the monumental light system present in the theatre from the maintenance and energy saving points of view.
