From August 28 to September 4, 2025, Eberhard Zangger and geodata specialist Alper Aşınmaz undertook a week-long research trip to archaeological sites in western Türkiye. They covered a total of 2,500 kilometers. The focus was on the Hittite spring sanctuary of Eflatunpınar east of Lake Beyşehir, which was examined from a scientific and technical perspective. Other stops included important settlement mounds, rock inscriptions, and fortifications, including the Luwian hieroglyphic inscription at Suratkaya, the Bronze Age tombs of Müsgebe, and the cyclopean wall of Kuşadası. In Selçuk, the researchers visited Ayasuluk Hill, where they were welcomed by Prof. Barış Gür and his team (photo courtesy). Gür also presented them with a copy of his newly published book “Thyateira II.” In Bergama, Zangger and Aşınmaz met with former mayor Sefa Taşkın, who has already published five books on the Luwian culture. The excursion ended with visits to Assos and Troy. There, the scientists inspected the museum, excavations, and those areas in the plain where Zangger has for over 30 years suspected the outskirts of the Bronze Age metropolis to be buried under alluvial sediments.
