In the 2nd millenium B.C. the Hittites established a big empire that reached from western Anatolia to the Egyptian empire. Their capital Hattusa is a very big area with several monumental buildings. The Lion Gate is an impressive example. The Hittite origin was central Europe. Their language shows close connections to Latin. In the 3rd millenium B.C. they arrived in Anatolia. They first appear in cuneiform inscriptions of the Assyrians who had several trade centers in Anatolia. From them they took the cuneiform writing, but also developed their own writing, which was used for special purposes. Many clay tablets with cuneiform inscriptions tell a lot about their life and history. UNESCO world heritage.
