The Odeon was built at the beginning of the 2nd century AD. The architect deviated from the usual construction method. Emperor Hadrian visited the city in 124 AD and ordered considerable reconstruction and decoration work.
The Odeon had a skené of very limited depth, even including the ädikulä. The foundations show how limited the depth of the whole building was. The foundation also shows an irregular distance between the roof-bearing columns mirrored around the centre. The cavea was divided into 5 kerkides. Over 2 stairs one reached the upper gallery. 7 rows of seats outlasted the times.

One entered the Odeon through entrances left and right of the skené and entered after passing a small anteroom the auditorium.
