A temple 6,000 years older than Stonehenge.
Göbekli Tepe in south-eastern Turkey was built around 9500 BC by hunter-gatherers, before farming, pottery or metal. T-shaped limestone pillars up to 5.5 metres tall, carved with animal reliefs, stand in circles. The site upends an old assumption: perhaps agriculture arose to feed such gathering places, rather than the other way round.
Useful: When a find flips the order 'first farming, then culture', it's time to check your model.
