The Southeastern Anatolian Project is Turkey's largest and most multifaceted development project, and also, one of the largest development projects in the world. The project includes active farming with extensive irrigation systems and electricity production, alongside of which are the tourism, mining, petrol, education, health, communication, industry and transport sectors. This project will also bring with it a change in climate in the area. Gazi Antep, located on a wide and fertile plain cultivated with extensive olive groves and vineyards, produces a variety of agricultural crops. It is especially known throughout Turkey for its excellent pistachios.
Industry also contributes to the local economy.
The 36 towers of the city's fortress were originally constructed in the Justinian era and were later rebuilt by the Seljuks. The Archaeological Museum has important items from Neolithic, Hittite, and Roman times. A Hittite sculpting school was centered inYesemek, where the 200 works of art on view reveal the beauty of Hittite art. The site's finds, including immense bas reliefs, have been moved to the Museum of Anatolian Civilizations in Ankara. The mosaics from the Roman period are well worth seeing.
