 Given the size of the empire, there are relatively few remains of Hittite art.These include some impressive monumental carvings, a number of rock reliefs, as well as metalwork, in particular the Alaca Höyük bronze standards, carved ivory, and ceramics, including the Hüseyindede vases.The Sphinx Gates of Alaca Höyük and Hattusa, with the monument at the spring of Eflatun Pınar, are among the largest constructed sculptures, along with a number of large recumbent lions, of which the "Lion of Babylon" statue at Babylon is the largest, if it is indeed Hittite.
