Thassian marble, considered in antiquity to be one of the purest marbles, is being used in the restoration which aims to reproduce the theatre's original appearance.
To this end, sections of the koilon (the auditorium), the parodoi (the side entrances between the skene and the audience) and the skene are being redressed in the famous marble.
The restoration is being financed by a private quarrying company.
