The basalt blocks with a seven-line Luwian inscription was found in situ as the doorjamb at King's Gate (see first image below). Unfortunately this block was destroyed after the excavations were completed. Several small fragments of it are in Anatoalian Civilizations Museum and one fragment is in British Museum. The doorjamb across the gate was not inscribed. The block was 0.85 cm high and 1.75 meters wide. Author of the inscription is ruler (tarwani) Katuwa, the Country-Lord of Karkamis and it is a building inscription and dedication to gods Tarhunza, Karhuha, and Kubaba. Katuwa gives his genealogy as the son of [Country-Lord Suhi], the Grandson of Country-Lord Astuwalamanza. Dates to 10th-9th centuries BCE.
