Kerkenes (or Kerkenes Dağ; both names are modern) is the largest pre-Hellenistic site from the Anatolian Plateau (Turkey) – 7 km (4 mi) of strong stone defenses, pierced by seven gates, that enclose 2.5 km² (1.0 sq mi). It is located about 200 km (120 mi) east from Ankara (35.06E, 39.75N), between the towns of Yozgat (W) and Sorgun (E).
