A tell on the upper Meander River of southwestern Anatolia (western Turkey) which has yielded evidence from the Chalcolithic to Late Bronze Age and of a culture contemporary with the Hittite empire. It is thought to have been the capital of the 2nd-millennium BC state of Arzawa. From the Chalcolithic, there was a cache of sophisticated copper tools and a silver ring, the earliest known use of that metal. Buildings that were religious shrines have been uncovered, almost unknown in Anatolia at those times. Rectangular shrine chambers were arranged in pairs, with ritual installations recalling the Horns of Consecration and Tree, or Pillar, cults of Minoan Crete. A palace building at the same site, dating from the Middle Bronze Age (c 1750 BC), Beycesultan's most prosperous period, had reception rooms at first-floor level, also in the Minoan manner. In common with most other Bronze Age buildings in Anatolia, its walls were composed of a brick-filled timber framework on stone foundations. The private houses of this period at Beycesultan were all built on the megaron plan. The whole settlement and a lower terrace on the river was enclosed by a perimeter wall. The town was violently destroyed and though it was rebuilt, it remained relatively poor into the Late Bronze Age.
