Göbekli Tepe: the ancient temple that changed our view of the beginning of civilization

by Sean McLachlan on


On a dusty hilltop in southwestern Turkey is an ancient temple that shouldn’t exist.

In 9,000 BC, people set up a series of round buildings decorated with giant “T”-shaped pillars carved with pictures of animals and humans. The buildings are 10-30 meters in diameter with a taller pair of pillars in the center and smaller ones at regular intervals around the circumference. The pillars range from 3-6 meters tall and weigh 6-10 tons each.

The hauling, cutting, and setting up of the pillars would have taken a huge amount of work, especially considering that 11,000 years ago people had no metal tools, no agriculture, not even any pottery. The temple at Göbekli Tepe has taught us that people were setting up major buildings before they even lived in towns. It’s turned out idea of prehistory upside down.

Now Göbekli Tepe is undergoing conservation by the Global Heritage Fund in order to preserve it for future study and protect it from looters.

One of the most intriguing aspects of Göbekli Tepe is that only about 5 percent of the site has been excavated. Who knows what this temple, built by hunter-gatherers 6,000 years before Stonehenge, will teach us next?

Stanton Drew stone circles yield more clues to the past

by Sean McLachlan on


A geophysical survey at the three stone circles at Stanton Drew near Bath, England, has uncovered more details about the prehistoric monuments.

This is Bath reports that subsurface imaging has added to a similar survey done in 1997. That survey revealed that the largest of the three circles was surrounded by a ditch with a wide entrance. The new survey, done with more modern equipment, discovered a second, smaller entrance. Archaeologists also found that one of the smaller stone circles stood on a leveled platform.

Stanton Drew’s main circle is more than 110 meters in diameter, making it the second largest stone circle in the UK, bigger than Stonehenge and second only to Avebury. The main entrance of its surrounding ditch faced a smaller stone circle to the northeast. Further away to the southwest was a third circle. Inside the main circle were nine concentric rings of wooden posts. These rings may have served as a sort of calendar marking important celestial events such as solstices and equinoxes. The megaliths of the three stone circles served a similar function.

Local folklore says the stones are a wedding party tricked by the Devil into celebrating on a Sunday. Stone circles have accumulated lots of folklore and several are said to be petrified people, including the Rollright Stones.

The complete archaeological reports are available here.

Was this strange stone a prehistoric calendar?

by Sean McLachlan on


This odd stone may look like an unusual product of nature, but it’s actually a monument from about 4,000 years ago called a menhir. Archaeologists have long debated what menhirs were for, perhaps boundary markers or gravestones or something else. Now experts are saying this one, at Gardom’s Edge in the Derbyshire Peak District, England, may be a prehistoric calendar.

Archaeoastronomers, who study astronomical alignments in ancient monuments, studied the stone and found that where the sun hit the slanted side may have acted as a marker for seasons. Other prehistoric remains are nearby, including the mysterious carvings shown below.

Local Bronze Age people are believed to have kept their herds in the higher hills during summer and moved to the warmer valleys when winter set in. This handy calendar would have told them when to move their herds. While the researchers say this sundial may be unique, some other megalithic monuments have astronomical alignments, the most famous being Stonehenge. Megalithic monuments such as stone circles and menhirs can be found all over the British Isles and make for some interesting stops while hiking. Trails such as the Ridgeway Trail pass by several.

The Peak District is one of England’s most beautiful natural spots and Gardom’s Edge is a favorite spot for rock climbing.

Petrified Forest National Park expands by 26,000 acres

by Sean McLachlan on


The Petrified Forest National Park in Arizona just got bigger to the tune of 26,000 acres.

After years of negotiation, the National Park Service bought the land from a ranching family, the Daily Democrat reports. This land had been enveloped by the park when it expanded from 93,500 acres to 218,500 acres in 2004.

The park is famous for its colorful petrified trees scattered across the landscape. The scenery is equally colorful, with rugged hills striated with differently hued stone.

Since the new acquisition is remote ranching land closed to visitors, it should prove a treasure trove to archaeologists and paleontologists. Traces of prehistoric Native Americans, such as arrowheads and petroglyphs (rock art) are common finds in the park, and many dinosaur bones have also been found. Scientists get first dibs on the area, so it will be at least a few years before it opens to the public.

Tomb of Stonehenge builder found?

by Sean McLachlan on


A prehistoric tomb discovered in Wales may be the grave of one of the builders of Stonehenge.

Archaeologists found the tomb at the Carn Menyn site in Wales, generally thought to be the quarry for the so-called “bluestones” used for the inner circle of Stonehenge in 2300 BC.

The tomb is a passage grave, a cigar-shaped enclosure of stone that was once covered in earth. The tomb is in ruins and was looted in antiquity. Some organic material has been found and this will be carbon dated. Passage graves were common for elite members of society in the Neolithic.

The tomb was set atop a henge, a circular ditch and embankment that had a pair of bluestones are set upright at one end, reminiscent of the pairs of bluestones at Stonehenge.

It’s a mystery why the builders of Stonehenge would choose to drag stones weighing two to four tons more than 150 miles. One of the archaeologists investigating the site suggests that Carn Menyn, shown to the right, had religious significance because of the many natural springs in the area. The presence of the henge and tomb suggest the place did indeed have religious and cultural importance.

The excavation continues.
