The ancient theatre of Thassos is built inside a natural cavity of the hill and leaning against the wall according to Hippocrates it must have been built here as early as the 5th century B.C. The beginning of the 3rd century B.C. saw the building of the scene with a marble front. The proscenio was dedicated by the Thassian Lysistratos (son of Kodes) to Dionysus. A whole pillar and various other sections of the forestage are saved to this day. Those years the theatre was used for theatrical and musical performances. Later in the Roman era the orchestra pit and the edolia (rows of seats) were renovated. On several seats one can still see inscribed names, which indicates that people used to reserve their seats. After the 1st century A.D. the theatre was used for «hunts» and gladiatorial combats. Among the usual combats there were also combats between pairs of riders. The orchestra pit was turned into an arena and, in mid-f century A.D. Eragoras (son of Eufrillos) raised a parapet of railings the bottom of which was embedded into marble slabs to protect the audience from wild beasts.
