Chamber “B” is the eastern, open–to–the–air, chamber at Yazilikaya (“Inscribed Rock”) in Turkey. It seems to be a memorial to the Hittite king Tudhaliya IV (1250–1220 B.C.) that was erected by his son Shupiluliuma II.
Yazilikaya is composed of an initial sanctuary, and three chambers, labeled A, B, and C. Only A and B are open to the public and the rock walls of each of these open air chambers are lined with carved reliefs of gods, goddesses, and kings.
