Perga or Perge (Greek: Πέργη Perge, Turkish: Perge) was an ancient Greek city in Anatolia, once the capital of Pamphylia Secunda, now in Antalya Province on the southwestern Mediterranean coast of Turkey. Today, it is a large site of ancient ruins 15 kilometres (9.3 mi) east of Antalya on the coastal plain. An acropolis located there dates back to the Bronze Age. Perga was an ancient and important city of Pamphylia, between the rivers Catarrhactes and Cestrus (Turkish Aksu Çayı). A treaty between the Hittite Great King Tudhaliya IV and his vassal, the king of Tarhuntassa, defined the latter's western border at the city "Parha" and the "Kastaraya River". The river is assumed to be the classical Cestrus. West of Parha were the "Lukka Lands". Parha likely spoke a late Luwian dialect like Lycian and that of the neo-Hittite kingdoms. Perge returns to history as a Pamphylian Greek city, and with Pamphylia came under successive rule by Persians, Athenians, and Persians again. Alexander the Great, after quitting Phaselis, occupied Perge with a part of his army. The road between these two towns is described as long and difficult. Alexander's rule was followed by the Diadochi empire of the Seleucids, then the Romans. Perge gained renown for the worship of Artemis, whose temple stood on a hill outside the town, and in whose honour annual festivals were celebrated. The coins of Perge represent both the goddess and her temple. In 46 A.D., according to the Acts of the Apostles, St. Paul journeyed to Perga, from there continued on to Antiocheia in Pisidia, then returned to Perga where he preached the word of God (Acts 14:25). Then he left the city and went to Attaleia. As the Cestrus silted up over the late Roman era, Perga declined as a secular city. In the first half of the 4th century, during the reign of Constantine the Great (324-337), Perga became an important centre of Christianity, which soon became the official religion of the Roman Empire. The city retained its status as a Christian centre in the 5th and 6th centuries. Perga is today an archaeological site and a tourist attraction. There were numerous excavations and discoveries since 1946. Ancient Perge, one of the chief cities of Pamphylia, was situated between the Rivers Catarrhactes (Düden Nehri) and Cestrus (Aksu), 60 stadia (about 11.1 kilometres (6.9 mi)) from the mouth of the latter; the site is in the modern Turkish village of Murtana on the Suridjik sou, a tributary of the Cestrus, formerly in the Ottoman vilayet of Konya. Its ruins include a theatre, a palaestra, a temple of Artemis and two churches. The temple of Artemis was located outside the town. Many of the coins struck in the city portrayed both the goddess and her sanctuary. Another big ancient city in the area is Selge, Pisidia, located about 20km to the northeast. The Perge has been dubbed as “Turkey’s second Zeugma” for the alluring appearance of the mosaics that have been unearthed so far. In 2003, archaeologists discovered well-preserved Greek mosaics showcasing Oceanus and Medusa. In 2017, discovered a mosaic depicting the sacrifice of Iphigenia.
