Aspendos theatre is known to be the best-preserved theatre of antiquity located in Antalya, Turkey and built in 155 AD by the architect Zenon. It has a diameter of 96 metres and provide seating for 12,000 people. The theatre was periodically repaired and used as a caravanserai by Seljuqs. It was converted into a palace by the Seljuqs of Rum in 13th century.
Although the theatre is the main reason for a visit to Aspendos there are more ruins to explore over a vast hilly area. The city surrendered to the Romans in 190 BC and toward the end of the Roman period the city began a decline that continued throughout Byzantine times.
