Hattusa is a huge complex site just on the outskirts of the modern village of Boğazkale in Turkey. Hattusa was the capital of the Hittite Empire occupied by the Hatti from circa 2500BC onwards. The Hattusa Sphinx on display in the Pergamon Museum belonged to a pair of sphinxes from the Sphinx Gate of the Yerkapi rampart at Hattusa which date to circa 1400BC.
