The Taş Tepeler project in southeastern Turkey, centered around Şanlıurfa Province, involves the excavation of multiple prehistoric sites dating back to the Pre-Pottery Neolithic period (approximately 10,000–7,000 BCE). These sites are significant for the occurrence on some of them of monumental T-shaped pillars and the insights they provide into the transition from hunter-gatherer societies to settled communities. The project currently encompasses the following excavated sites:
- Göbeklitepe: The most famous site, a UNESCO World Heritage Site, known for its large circular enclosures with T-shaped limestone pillars, some decorated with animal reliefs. Excavations began in 1995 and continue to reveal structures from around 9600–7000 BCE.
- Karahantepe: Located about 46 kilometers from Şanlıurfa, this site features over 250 T-shaped megaliths and evidence of both ritual and domestic use. Excavations started in 2019 and have uncovered realistic human statues and enclosures.
- Sayburç: This site has yielded a notable relief depicting a five-figure scene with humans, leopards, and a bull, considered one of the earliest narrative carvings from the Neolithic. Some of the buildings had T-shaped pillars, some in the shape of human figures. Excavations are ongoing.
- Harbetsuvan Tepesi: Situated 7 kilometers southwest of Karahantepe, it’s a smaller site (about 5 decares), currently under excavation.The stone structures, partially destroyed by later damage, consisted of rectangular buildings, at least one of which was equipped with a pair of stone pillars at the centrer. Stone construction included an important finding: a seated male sculpture resembling those recovered at Göbeklitepe and Karahantepe
- Gürcütepe: Part of the initial seven sites announced in 2021, it’s being explored for its Neolithic remains, though specific findings are less publicized.
- Çakmaktepe: Another of the original seven, this site is under active excavation, contributing to the broader understanding of the region’s prehistory.
- Sefertepe: Included in the initial phase, it’s being excavated to uncover T-shaped obelisks and related structures.
- Yeni Mahalle Mound: Also among the first seven, this site near Şanlıurfa is part of the ongoing digs, revealing early settlement evidence.
- Kurttepesi: One of the twelve identified sites with T-shaped pillars, currently under excavation as part of the expanded project.
- Taşlıtepe: A site similar in scale to Harbetsuvan, it’s being excavated to explore its Neolithic features.
- Ayanlar Höyük: Located 30 kilometers west of Şanlıurfa, it’s under investigation, though no T-shaped stelae have been found yet, suggesting it may have been a cult center.
- Yoğunburç: Added to the excavation list, it’s being studied for its contributions to the Neolithic narrative.
- Söğüt Tarlası-Biris Mezarlığı is a site located about 32 km northwest of Şanlıurfa, just south of the city center of Bozova
