Many disputes have risen concerning the original structure of the theatre. Apparently the biggest part of the theater was originally made of wood but it was later rebuilt in stone. In 330 B.C. stone seats were added that could host up to 17,000 people. The stage was reconstructed over the centuries and most of the ruins that we see today come from the Roman times. At its final form, the lower part had 13 more sections that were separated by steps and 32 rows of seats covering the perimeter of the orchestra. The upper part had another 32 rows of seats covering only the centre. Later on a third part was added. Today, only 20 of these sections have been preserved. The inscriptions on some of the thrones reveal that they belonged to elected rulers, while the other seats were intended for citizens. However, the most impressive seat was bearing the inscription Priest of Dionysus Eleftherius carved with bunches of grapes. Important efforts have started over the last years so that the ancient theatre of Dionysus will be renovated and host theatre performances again. Source: www.greeka.com
