Kültepe, where documents were discovered that date the history of Kayseri back 6,000 years, 21 km from the Kayseri city centre. The Kültepe Ruins (Kültepe Ören Yeri) consist of a mound and the surrounding Karum, the ruins of the first city founded by the Hittites in Anatolia, as well as the ruins of administrative and religious buildings, houses, shops, and workshops. The centre of the karums, large trade colonies established by the Assyrians, was the Karum in Kültepe, and it oversaw the other karums. Kültepe stands out as the home of the first written tablets in Anatolia and it was the world’s first organized trade centre. Written in Assyrian cuneiform, these tablets contain letters, bills, seals, and treaties that reveal the political and legal relations of the period. These tablets were added to the UNESCO Memory of the World Register in 2015.
