Seven thousand years older than Stonehenge, Gobekli Tepe is a ring of standing stones built by hunter-gatherers in what is now Turkey.
This is a huge deal because before it was discovered in 1993, archaeologists thought that temple complexes came after agriculture.
Compared with Stonehenge, they are humble affairs. None of the circles excavated (four out of an estimated 20) are more than 30 metres across. T-shaped pillars like the rest, two five-metre stones tower at least a metre above their peers. What makes them remarkable are their carved reliefs of boars, foxes, lions, birds, snakes and scorpions, and their age. Dated at around 9,500BC, these stones are 5,500 years older than the first cities of Mesopotamia, and 7,000 years older than Stonehenge.
What’s even more remarkable is that the temple is in fantastic condition. The builders seem to have covered it completely in tons of soil soon after they built it.
