The theatre was located on the northeast side of Priene. It was built during the Hellenistic times (4th century B.C.). Later on, Romans restructered the theatre in the 2nd century A.D. This alteration changed the whole Hellenistic character of the theatre.
This is one of the oldest theatres in Anatolia. The floor of the orchestra is made of hardened soil. The place for orchestra is surrounded by five marble armchairs with an altar in the middle.
The building is 18m long and has 11 pilars with 10 half columns at the front. The theatre was horse-shoe shaped and 5,000 seat swere available for the spectators.
The auditorium had 50 tiers, but only bottom 8 remained till today. The elevated altar in the orchestral place had a table shape and during the performances for Dionysos, the offerings were laid on the altar.
The theater reached to our time in a well preserved condition.
