Aspendos boasts one of the best preserved ancient theatres of antiquity. The theatre of Aspendos was built in 155 AD during the rule of the Roman Emperor Marcus Aurelius and could seat between 15,000 and 20,000 spectators. Because the stage area was later used as a caravanserai (a roadside inn) in Seljuk times, it was continuously repaired and maintained. Thus, the Aspendos Theatre has been able to survive to this days without losing almost any of its original qualities.
