Located on the 2nd kilometer of the road turning north from the 44th kilometer of the Antalya - Alanya highway, Aspendos is famous for having the best preserved Roman theater not only in Anatolia but also in the entire Mediterranean world. The city was founded on a hill plain near Köprüçay (Ancient Eurymedon), one of the largest rivers in the region. Aspendos owes its access to the Mediterranean and its development to the nearby river and thus to the fertile lands around it. Today, the theater and waterways are mostly visited. The ruins of other buildings belonging to the city are located on the plain of the hill where the theater rests. 

Historians tell of a battle between the Greeks and Persians in 467 BC on the banks of the river that flows near the city, called the Battle of Eurymedon, which the Greek side won. Although Aspendos tried to resist Alexander the Great by fraudulent means, they eventually surrendered and accepted the tax debt in exchange for gold and the famous horses bred in the city. After Alexander's death, the city came under the rule of the Ptolemies, and its most brilliant period was undoubtedly the Roman Imperial period, when the famous theater and waterways were built.

The Aspendos Theater is one of the most distinguished representatives of the Roman Period theaters today, both for its architectural features and its good preservation.Dedicated to the gods and emperors of the period, the structure exhibits the last lines of Roman theater architecture and construction technique.Aspendos theater, one of the magnificent structures of its era, could accommodate 15-20 thousand people.It was built during the reign of Emperor Marcus Aurelius (161-180 AD) by the architect Zenon, son of Theodoros. Greek and Latin inscriptions on both sides of the entrance indicate that it was built by two rich brothers of the city, Curtius Crispinus and Curtius Auspicatus.Besides the theater, the most important ruins of the city that can be visited are the waterways.The Aspendos waterway system is one of the best surviving examples of ancient waterways. 
The general view is formed by the water pressure towers at both ends of the north-south arched bridge, which is about 1 kilometer long. While the city's water was collected in pear-shaped cisterns carved into the bedrock, which can be seen in places on the hill, in the 2nd and 3rd centuries AD, the waterway system was developed together with all the buildings and the water was obtained more regularly. The agora, basilica, monumental fountain, parliament building, monumental arch, street and Hellenistic temple, which are the buildings of the city center, are the ruins to be seen on the hill surrounded by city walls in places.
