Description

　　The ancient city of Aspendos is located in Southern Turkey, in the ancient Pamphylia region by the Eurymedon (Köprüçay) river. The acropolis lies about 60 m. above sea level and sits on a flat-topped hill with many surviving monuments including the Nymphaeum, Basilica, Market Building and Odeion. 

　　The Eurymedon used to be a navigable river and gave access to the city. This was the main reason for the city‟s prosperity. Both the archaeological remains and the historical sources confirm that Aspendos had entered upon the stage of ancient world events by the 5th  century BC with the arrival of the Persians to Pamphylia and that it continued to retain its importance until, and after, Alexander‟s control of Asia Minor. 

　　The earlier archaeology is currently being investigated, and recent findings carried the history of the city back even further. Recent surveys and excavations brought up material cultures from the Early Iron Age. The monumental buildings are mainly from the Hellenistic and Roman Period. Currently, it is known that there was continuous settlement right through to the Byzantine and Seljuk periods.

　　The site is visited by approximately 400.000 people every year, mainly because of its magnificent Roman theatre. “This is not like anything that I ever saw before.” This is how the British archaeologist David George Hogarth had described the Aspendos Theatre in 1909 in a paragraph which continues as follows: “You may have seen the amphitheatres in Italy, France, Dalmatia and Africa; temples in Egypt and Greece; the palaces in Crete; you may be sated with antiquity or scornful of it. But you have not seen the theatre of Aspendos.” 

　　This description is still valid today, because the site of Aspendos houses the best preserved ancient theatre of the world. In addition, this richly decorated monument bears the traces of different historic periods including the Roman and the Seljuk periods. It was initially built during the reign of the Roman emperor Marcus Aurelius, between 160-180 A.D.  The inscription on the western entrance wall records that the architect was Zenon, son of Theodorus and it was the gift of two rich brothers; A.Curtius Crispinus Arruntianus and A.Curtius Crispinus. 

　　Like most theatres in Asia Minor, the majority of the cavea or spectator tribune is dug out of the eastern slope of the acropolis whereas the rest is supported by artificial subtractions, a stone-built arch and vault system. 

　　The monument is among the biggest of its kind, with a façade of approximately 100 meters wide and 22 meters high. What makes it unique is the impressive level of preservation and the richness of its architectural decorations. The new investigations have revealed that the capacity of the theatre was 7300-7600 people (45cm seating width per person). This number could be up to 8500 people, if stairs had been used as seat places in crowded performances in Ancient Times. The cavea is divided in two parts by a horizontal passage called the diazoma. The lower section contains 20 rows of seat, while the upper one has 21 rows. The main entrances to the lower cavea are through two vaulted parodoi, linking the stage building to the cavea. The actual scaenae frons or stage is flanked by two towers, providing access to the seating rows situated higher up in the auditorium. In addition, a system of gates in the exterior wall of the cavea provided additional options to access the cavea. Unique also is the covered gallery raised above the whole perimeter of the cavea, offering shelter from the elements to those who wished to take a brake from the spectacles. Although partially reconstructed, it is the best preserved example in Asia Minor and beyond. 

　　The two-storied stage building, which is adorned with exquisite architectural ornamentation, still stands to its full height. The stage was accessed through five doors. The central gate is the largest one and is flanked by two doors of decreasing dimensions on either side. Projecting socles, separating the doors from one another, are still preserved. The formed the basis for the two-storied aediculated façade that formed the background of the actual stage for the actors, which is no longer preserved and was probably dismantled when the function of the building changed in post antique times. The façade itself was magnificently decorated and composed of highly decorated entablatures supported by monolithic columns. The friezes of the lower storey were decorated with garlands hung from bucrania, whereas a tendril frieze decorated those of the upper storey. They supported equally richly carved cornices, which were in their turn crowned by differently shaped pediments. In the middle over the central gate, the façade culminated in a large-scale relief. Although the fronts of the protruding elements of the façade are no longer there, the remaining elements still provide an excellent idea of the original monumental façade. The monument is also of extreme importance for understanding the use of acoustics in ancient theatres. The stage building of Aspendos Theatre was probably covered by a wooden roof, which has not survived. Seljuk restoration in the 13th century and the reuse of the monument as a palace for a short period during the time of Sultan Alaeddin Keykubat aided the preservation of this magnificent structure. The zigzag paintings in red, which are still visible today on many surfaces of the internal and external façade, are dated to this period.  Additionally, some of the windows on the inner part of the stage building were converted into gates to provide access to the southern part of the structure from the north tower. 

　　Although mainly known for its theatre by the general public and visitors, Aspendos‟ aqueducts, with their two unique siphons, have been a source of extreme fascination for researchers. The aqueducts brought water to the city from the mountains 15 km to the north. The water, which was carried by the arcades, and at some points by the underground pipe drains, was vital not only for Aspendos but for the whole of the Pamphylian plain. It was thanks to this water that the city and its rural surroundings were fertile and rich in grain. The water was brought to the city centre by means of this aqueduct from two sources, namely Gökçeler and Pınarbaşı at about 500 m above sea level and 19 km away. Bean suggests, after study of an epigraphic source, that the Aspendos‟ aqueducts were erected by Tiberius Claudius Italicus at a cost of 2 million Denarii in the second century AD. The inverted siphons of the aqueduct, which are approximately 30 m high, made it possible to cross the 1.7km wide valley between the mountains to the north and the acropolis. The inner dimensions of the water channels were 55-60 cm wide and 90 cm high. The water channels of the siphons are of stone. The siphons rise at an angle of 55 degrees and the 924 m distance between them is traversed by arches that are 5.5 m wide space. The arches are 15 m high in the deepest point of the valley. 

　　This structure, with these measurements and in its current condition, is one of the highest Roman constructions. Aspendos‟  aqueducts are similar to two structures, which are already on the UNESCO World Heritage List: the Pont du Gard aqueducts, which are higher than the one in Aspendos with a height of 48.77 meters; and the aqueducts of Segovia in Spain, which are 28.5 meters. 

　　However none of these structures contain the siphons, which are extremely well preserved at Aspendos. Similar siphons can be found in Lyon (Mont d‟Or, Brévenne and Gier), however these do not provide any insight into their  building  technique or the use of these structures. The siphons in Aspendos allow researchers to make further discoveries on how it might have functioned. Moreover, the length of the still standing aqueducts of Aspendos is more than the ones in Segovia and Pont du Gard.
