The basalt blocks with a seven-line Luwian inscription were 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 the Anatolian Civilizations Museum and one fragment is in the British Museum. A few small fragments were found during the latest excavations. The doorjamb across the gate was not inscribed. The block was 0.85 meter high and 1.75 meters wide. Author of the inscription is ruler (tarwani) Katuwa, the Country-Lord of Karkami 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 the 10th-9th century BCE.
