Aspendos Theater is one of the most distinguished representatives of the Roman Age theaters today, with its architectural features and well preservation. Dedicated to the gods and emperors of the era, the building exhibits the last lines of Roman theater architecture and construction technique. Aspendos theater, one of the magnificent structures of its period, could accommodate 15-20 thousand people. It was built by the architect Zenon, son of Theodoros, during the reign of Emperor Marcus Aurelius (AD 161-180). It is understood from the Greek and Latin inscriptions that the city was built by two rich brothers named Curtius Crispinus and Curtius Auspicatus at two moments of the entrance. Besides the theater, the most important ruins of the city that can be visited are the waterways. Aspendos waterway system is one of the best preserved examples of ancient waterways. Its general view is the water pressure towers at both ends of the north-south arched bridge, which is approximately 1 kilometer long. While the water of the city is collected in pear-shaped cisterns carved into the bedrock that can be seen from time to time on the hill, İ.S. In the 2nd and 3rd centuries, the waterway system was developed together with all the buildings and the water was obtained more regularly. The agora, the basilica, the monumental fountain, the assembly building and the monumental arch, the street and the Hellenistic temple are the ruins of the city center on the hill where the theater leans and is surrounded by city walls in some places.
The fact that a city on such a small scale prints the most valid money of the entire Mediterranean world and its navy with monumental structures can easily be explained in its economy. The most important export product that keeps the city economy alive is the salt obtained from the nearby Lake Kapria, which is dried and used in cotton agriculture. The most important source of income of the city was salt, which was sent to other Mediterranean markets via the river, which is convenient for transportation, along with other export products. In addition, viticulture and consequently winemaking, olive and olive oil and other grain products and fresh fruit were the other agricultural export products of the city. Historians write that the horses bred in Aspendos are the most sought after horses in the entire Near East and Mediterranean world. Aspendos is one of the cities that continued its existence during the Byzantine and Seljuk periods. In the famous theater, it is possible to see the traces of Seljuk period repairs, especially in the monumental door extension in the middle of the facade and in the dark red zigzag patterned plaster coating on the facade.
