Six miles from Urfa, an ancient city in southeastern Turkey, Klaus Schmidt has made one of the most startling archaeological discoveries of our time: massive carved stones about 11,000 years old, crafted and arranged by prehistoric people who had not yet developed metal tools or even pottery. The megaliths predate Stonehenge by some 6,000 years. The place is called Gobekli Tepe, and Schmidt, a German archaeologist who has been working here more than a decade, is convinced it's the site of the world's oldest temple.
"Guten Morgen," he says at 5:20 a.m. when his van picks me up at my hotel in Urfa. Thirty minutes later, the van reaches the foot of a grassy hill and parks next to strands of barbed wire. We follow a knot of workmen up the hill to rectangular pits shaded by a corrugated steel roof—the main excavation site. In the pits, standing stones, or pillars, are arranged in circles. Beyond, on the hillside, are four other rings of partially excavated pillars. Each ring has a roughly similar layout: in the center are two large stone T-shaped pillars encircled by slightly smaller stones facing inward. The tallest pillars tower 16 feet and, Schmidt says, weigh between seven and ten tons. As we walk among them, I see that some are blank, while others are elaborately carved: foxes, lions, scorpions and vultures abound, twisting and crawling on the pillars' broad sides.
Schmidt points to the great stone rings, one of them 65 feet across. "This is the first human-built holy place," he says.
From this perch 1,000 feet above the valley, we can see to the horizon in nearly every direction. Schmidt, 53, asks me to imagine what the landscape would have looked like 11,000 years ago, before centuries of intensive farming and settlement turned it into the nearly featureless brown expanse it is today.
Prehistoric people would have gazed upon herds of gazelle and other wild animals; gently flowing rivers, which attracted migrating geese and ducks; fruit and nut trees; and rippling fields of wild barley and wild wheat varieties such as emmer and einkorn. "This area was like a paradise," says Schmidt, a member of the German Archaeological Institute. Indeed, Gobekli Tepe sits at the northern edge of the Fertile Crescent—an arc of mild climate and arable land from the Persian Gulf to present-day Lebanon, Israel, Jordan and Egypt—and would have attracted hunter-gatherers from Africa and the Levant. And partly because Schmidt has found no evidence that people permanently resided on the summit of Gobekli Tepe itself, he believes this was a place of worship on an unprecedented scale—humanity's first "cathedral on a hill."
With the sun higher in the sky, Schmidt ties a white scarf around his balding head, turban-style, and deftly picks his way down the hill among the relics. In rapid-fire German he explains that he has mapped the entire summit using ground-penetrating radar and geomagnetic surveys, charting where at least 16 other megalith rings remain buried across 22 acres. The one-acre excavation covers less than 5 percent of the site. He says archaeologists could dig here for another 50 years and barely scratch the surface.
Gobekli Tepe was first examined—and dismissed—by University of Chicago and Istanbul University anthropologists in the 1960s. As part of a sweeping survey of the region, they visited the hill, saw some broken slabs of limestone and assumed the mound was nothing more than an abandoned medieval cemetery. In 1994, Schmidt was working on his own survey of prehistoric sites in the region. After reading a brief mention of the stone-littered hilltop in the University of Chicago researchers' report, he decided to go there himself. From the moment he first saw it, he knew the place was extraordinary.
