Mysterious monument found next to Stonehenge

by Sean McLachlan on

Britain’s most interesting monument just got a whole lot more interesting.

Archaeologists using subsurface imaging have discovered evidence of a circle of wooden posts about the same size as Stonehenge and just 900 meters (2,950 feet) away from it.

The Stonehenge Hidden Landscape Project plans to map features hidden under the surface in an area totaling 14 square kilometers (8.7 sq miles) around the famous monument. The mysterious feature was found only two weeks into the three-year survey.

The team picked up traces of postholes, where heavy wooden poles had once been sunk into the earth. The soil in these holes is of a different density than the undisturbed soil around them and show up on the subsurface imaging. The ring of posts appears to have had two openings opposite one another and was encircled by a ring of pits a meter wide. Archaeologists say it was built about 2,500 BC, about the same time that the builders of Stonehenge switched from using timber to using stone.

Project leader Professor Vince Gaffney of the University of Birmingham said, “When you see that as an archaeologist, you just look at it and think, ‘that’s a henge monument’ – it’s a timber equivalent to Stonehenge. The monument is one of the most studied monuments on Earth but this demonstrates that there is still much more to be found. The presumption was this was just an empty field – now you’ve got a major ceremonial monument looking at Stonehenge”.

The BBC has an interview with Prof. Gaffney and a computer reconstruction of the monument here. His team’s discovery comes just weeks after the start of excavations at Marden Henge, a stone circle ten times bigger than Stonehenge. It’s shaping up to be a good summer for archaeologists!

Archaeologists explore stone circle ten times larger than Stonehenge

by Sean McLachlan on

Move over Stonehenge, there’s a bigger stone circle in town.

Archaeologists are busy excavating Marden Henge, a giant stone circle and earthwork ten times larger than its more famous cousin. It’s not nearly as well-known, however, because all of its stones have been lost or buried. Traces of a giant earthwork and ditch that encircled the monument do survive, and archaeologists hope they’ll reveal secrets of England’s prehistoric past.

While everyone knows about Stonehenge, many people don’t realize there are nearly a thousand stone circles in the British Isles, from massive ones like Avebury (shown here) to smaller ones like the Rollright Stones. Marden Henge is in Wiltshire, close to Stonehenge and Avebury, and could provide clues to how and why they were constructed. The giant circle encloses about 15 hectares (37 acres) and has a mound at its center. Archaeologists plan to investigate both the central mound and the earthwork and ditch. The Neolithic farmers who built these monuments often put sacrifices in the surrounding ditches.

While there are no current plans for a visitor’s center at Marden Henge, there are plenty of other stone circles open to the public. Some of the more famous cater to visitors with interpretive signs and parking lots, while others simply stand in open fields, an enduring part of Europe’s ancient landscape. An excellent website to help you plan a visit is The Megalithic Portal, which includes information on stone circles and other megaliths such as barrows (tombs) and menhirs (individual standing stones) in the UK and all around the world.

Stonehenge, Machu Picchu top ‘most threatened’ wonders list

by Kraig Becker on

U.K. travel magazine Wanderlust has released their second annual list of the world’s most threatened wonders, with eight very popular attractions earning this dubious distinction for 2010.

Perhaps the two most eye catching destinations on the list are Stone Henge in the U.K. and Machu Picchu in Peru. The magazine actually describes Stonehenge as a “national disgrace” and rips the stone monument for being so detached from the rest of the ancient ruins in the area that loses some of the historical context. In the case of Machu Picchu, it seems the lost city of the Inca is a victim of its own popularity, with large crowds and over zealous tourists blamed for the sad state of affairs there.

The other destinations to make this year’s list include Wadi Rum, Jordan; Yangshuo, China; Tulum, Mexico; Jaisalmer, India; Timbuktu, Mali and the Bay of Fires, Tasmania. Each has their own unique issues to deal with ranging from too much tourist traffic, a lack of security and governmental struggles over access to the places.

Fortunately, Wanderlust doesn’t just point fingers, but also suggests some ways to solve the issues facing these popular attractions. For example, in the case of Stone Henge, they endorse a plan that has been put fourth to build an underground tunnel that wold link the stone monoliths to other nearby sites that are part of the same ancient compound. And as for Machu Picchu, they put the onus on the tour operators to ensure that their groups tread lightly and leave little trace of their passing on the fragile mountain environment and the centuries old citadel itself.

This list does a good job of drawing attention to the fact that many of these locations are suffering from being too popular. Perhaps good discussions about these issues will help make us all more aware of the problems and help preserve these sites for future travelers to enjoy as well.%Gallery-64352%

Avebury–more awesome than Stonehenge

by Sean McLachlan on

Everyone’s heard of Stonehenge, the enigmatic stone circle on Salisbury Plain, but just seventeen miles to the north stands an even more imposing monument–Avebury.

Actually it’s a whole landscape of monuments. For miles around the rolling fields are dotted with the burial mounds of forgotten chieftains, and many hilltops are protected by ancient ramparts. Avebury itself is a massive stone circle with two avenues running across the fields to a pair of smaller stone circles. The entire area has been designated a World Heritage Site.

Stonehenge is more self contained, a pretty picture and fascinating to stare at, but it suffers from familiarity, so much so that the Times Online listed it as one of the world’s five most overrated tourist attractions. Avebury is far more vast, and instead of walking along a cordoned path with hundreds of other visitors, you can wander through a prehistoric landscape away from the crowd.

Getting off the bus at the village of Avebury, you don’t have far to go to see the main monument, in fact you’re right in the middle of it. An impressive circle of stones (called a henge in scientific parlance) more than a thousand feet in diameter is surrounded by a deep ditch and earthen rampart. Two smaller henges stand inside the large one. An avenue flanked by smaller stones heads south, and there used to be another one headed west, although that’s all but disappeared thanks to the march of time. This main monument was started around 3000 BC, or five thousand years ago.

Considering the region’s history, it’s amazing any of the smaller stones survive at all. During the Middle Ages the local farmers got religion in a big way and decided to destroy this reminder of their pagan past. Easier said than done. Whole villages turned out to make huge bonfires to crack the stones, and then they hauled the pieces away and used them for local buildings, a common practice throughout England and seen especially along the route of Hadrian’s Wall, where the Romans were kind enough to make properly shaped stones instead of massive monoliths.

Destruction was as dangerous as it was difficult. Local legend says that one day a group of men were working to topple a large stone and it fell over, crushing one of the workers. In 1938 archaeologists dug up a fallen stone and found the skeleton of a man underneath. He carried some 14th century coins and the tools of a barber-surgeon (the jobs were the same back then). These folks, who cut hair, lanced boils, and utterly failed to find a cure for the plague, were considered to be quasi-magical, their strange arts necessary but somewhat suspect. It’s interesting that a magical person was brought along to destroy a magical place, and it’s no wonder his death became enshrined in local memory.

Fortunately much has been preserved or restored. A walk down the avenue of stones headed south from Avebury brings you to two more famous monuments.

%Gallery-72633%The field slopes down toward the south, and as you pass around the brow of a ridge a giant conical hill appears. This is Silbury Hill, a 130 ft. chalk mound erected around 2500 BC. Nobody is sure what it was for, but some researchers noticed it’s in a large circular valley that works as a natural amphitheater. I spoke to one of the site’s volunteers who participated in an experiment a couple of years ago. A group of musicians using reconstructed prehistoric instruments played them atop the hill while people stood at various locations around it. This woman stood a mile away and could hear all the instruments clearly, except the drums which were muffled due to the rain. She could even hear a song one of the musicians sang, picking out most of the words even though artillery practice was going on at the nearby military base!

On a ridge beyond Silbury Hill is West Kennet Long Barrow, a gallery of stones forming a long hall and four side chambers, with a larger chamber at the end. All of it is covered with earth to make a long artificial ridge atop the natural one. It was started around 3600 BC and remarkably some of the burials survived to the modern era. The first two rooms flanking the gallery held the remains of women, children, and the elderly. The next two contained adults, and the big room at the end had bones only of adult males. Were these warriors? Nobody knows, but it’s fun to speculate.

All in all, Avebury makes for a fun day of wandering. I suggest starting early and taking a good pair of walking shoes and an Ordinance Survey map. There are many smaller archaeological sites in the area worth visiting that only take a mile or so of walking to get to. The visitor center in town sells detailed maps.

5000 year old navigation system discovered

by Kraig Becker on

A primitive, yet highly effective, navigation system was used by ancient man to navigate their way across England and Wales historians claim, proving once again that ancient civilizations were far more sophisticated in their approach to engineering than was once thought.

According to this story from the Daily Mail, the 5000 year old “sat nav” system used stone monuments, often erected atop high hills, to point the way to similar points, sometimes as far as 100 miles away. This intricate network of stone monoliths, which includes Stonehenge, created a system that would allow ancient travelers to navigate across long distances with an accuracy of within 100 meters.

British Historian Tom Brooks used modern GPS systems to examine more than 1500 historical sites, and his findings were astounding. Each of the sites was connected to one another by vast geometric grid made of of isosceles triangles, in which each triangle has two sides of the same length, and pointed to the next settlement, thus allowing for simple and effective navigation across the landscape.

If Brook’s assertion that the system was created over 5000 years ago is correct, the use of geometry predates that of the Greeks, who were thought to have discovered that branch of mathematics. He also claims that it is the “world’s biggest civil engineering project” as well.

The implications of this theory are very interesting, and it does help to explain what the purpose of sites such as Stonehenge were used for, although their method of construction still remains a mystery. This is a fascinating story of how prehistoric man may have found their way across long distances.
