Yazılıkaya (Turkish: Inscribed rock) was a sanctuary of Hattusa, the capital city of the Hittite Empire, today in the Çorum Province, Turkey.

The left wall shows a procession of male deities, wearing the traditional kilts, pointed shoes and horned hats.

The processions lead to a central scene of the supreme couple of the pantheon: the storm-god Teshub and the sun-goddess Hebat.

Hebat's original consort was changed into her and Teshub's son (Sharruma) and she was later syncretized with the Hattic Sun goddess of Arinna.

A 2021 study concluded that the sanctuary depicted the cosmos including its three levels: earth, sky, and underworld; in addition to the cyclical processes: day/night, lunar phases, and summer/winter, which served as a lunisolar calendar.
