    Karatepe-Aslantaş Open-air Museum

    24 kilometres east from Kadirli district, Karatepe Castle is a unique example of defensive architecture as a frontier castle of Adanava –a city state that during Late Hittite Period in Anatolia. Its construction was ordered by “the region’s sovereign” Azatiwada in 8th century BCE to defend the city against attacks from the north.

    Archaeological importance of Karatepe-Aslantaş is due to its bilingual inscriptions (in Phoenician and Luwian) – also known as the Karatepe Bilingual and the Azatiwada inscription, it is frequently compared to the Rosetta Stone. Basalt steles and reliefs on its doors have inscriptions written both in Phoenician alphabet and Luwian hieroglyphics (being the longest text in this combination) it has played a very important role for the decipherment of the Luwian language.

    Located in the 4341-hectare national park bearing the same name, Karatepe-Aslantaş Archaeological Site (Karatepe-Aslantaş Arkeoloji Alanı) is a perfect example of successful archaeological conservation and welcomes visitors as the first and the biggest open-air museum of Türkiye. The site is surrounded by natural beauties, history, wildlife and the Aslantaş Dam.  

    Karatepe-Aslantaş Archaeologic Site was included in the UNESCO World Heritage Tentative List (UNESCO Dünya Mirasları Geçici Listesi) in 2020.
