The south western entrance of the Upper City of Hattusha is the Lion Gate, named for the two matched lions carved from two arched stones. When the gate was in use, during the Hittite Empire period between 1343-1200 BC, the stones arched in a parabola, with towers on either side, a magnificent and daunting image.
