Göbekli Tepe, in south-eastern Turkey, has monumental stone enclosures built about 11,500 years ago, thousands of years before the first cities, writing or states.
The site, near Şanlıurfa, has round and oval enclosures ringed by large T-shaped limestone pillars, the tallest more than 5 metres high. They are carved with foxes, boars, snakes, scorpions and vultures, and some bear human arms and hands, which suggests the pillars stand for stylised people. German archaeologist Klaus Schmidt recognised the site's importance in 1994 and began excavating in 1995. The oldest structures date to about 9500 BCE, when people in the region still lived by hunting and gathering wild plants. Schmidt saw it as a place where scattered groups met for rituals; later excavations also found houses, cisterns and heavy processing of wild cereals, so it was probably a settlement too. UNESCO made it a World Heritage Site in 2018.
