Kaman-Kalehöyük

{{refimprove|date=June 2011}} '''Kaman-Kalehöyük''' is a multi-period [[archaeological site]] in [[Turkey]], around 100km south east of [[Ankara]]. It is a [[tell]] or mound site that was occupied during the [[Bronze Age]], [[Iron Age]] and [[Ottoman Empire|Ottoman]] periods. Since 1986 it has been investigated by archaeologists from the [[Middle Eastern Culture Center in Japan]]. In 2005, [[metallurgy|metallurgical]] analysis by Hideo Akanuma of iron fragments found at Kaman-Kalehöyük in 1994 and dating to ''c''. 1800 BCE revealed that some of these fragments were in fact composed of carbon [[steel]]; these currently form the world's earliest known evidence for steel manufacture. ==External links== [http://www.jiaa-kaman.org/en/index.html Japanese Institute of Anatolian Archaeology] - official website {{Former settlements in Turkey}} {{coord missing|Turkey}}
