Prehistoric ruins and sites to visit

Prehistoric covers peoples who left no written record of their own, from the hunter-gatherers who raised the carved pillars of Göbekli Tepe around 9500 BC, through the first farming villages of Çatalhöyük and Khirokitia and the Neolithic builders of Malta, Orkney, Ireland and Wiltshire, to the Bronze Age towers of Sardinia and the Thracians and Dacians of the Balkans. What survives is stone: circles and standing stones, passage tombs and dolmens, temple walls, cliff-edge forts and villages with their stone furniture.
