Prehistoric stone circle discovered in Yorkshire

A stone circle that was once part of a prehistoric cairn has been discovered by a group of amateur archaeologists on Ilkley Moor, Yorkshire, England.

A cairn is a large pile of stones that marked the grave of an important individual in prehistoric times. These stones were often taken away by later farmers for building walls or cottages, and sometimes all that’s left is a circle of stones from the base, as is the case here. The team says the cairn measures 27 by 24 feet. It would have been pretty high back in its glory days.

One stone had a man-made circular impression archaeologists call a cup mark. These are found all over prehistoric Europe singly or in groups, but nobody knows what they mean.

The UK countryside is full of ancient remains. When I was hiking along Hadrian’s Wall and the East Highland Way I brought along Ordnance Survey maps not only to find my way but because many prehistoric sites are marked on them. I passed stone circles, Anglo-Saxon ring forts, crumbled castles, and much more. Take these maps along to make your walk through the countryside a walk through history.

The Yorkshire team has made numerous discoveries in recent months. Archaeology is understaffed and underfunded, and dedicated groups of amateurs help take up the slack. Archaeological societies exist in many towns throughout the world and are a great way to learn about the past. While members are amateur in the sense that they don’t make their living as archaeologists, they’re often well trained and knowledgeable. This is important so that when they make their discoveries they don’t harm the very sites they are trying to study and preserve.

Exploring the tunnels under the Western Front

The common image of the Western Front in World War One is of muddy trenches and artillery barrages. That was certainly the experience of most soldiers. But while huge armies slugged it out in the mud and ruin of France and Belgium, another war was going on underground. Sappers from both sides dug tunnels under enemy trenches, packed them with explosives, and blew them up.

The explosions were huge, like this one the British detonated under the German position on Hawthorn Ridge on 1 July 1916. The explosion used 40,000 pounds of high explosives and marked the beginning of the Battle of the Somme.

Sapping was extremely dangerous. Tunnels collapsed or got blown up by enemy mines. Sometimes mines intersected one another and there were hellish fights in the near darkness. Two good fictional portrayals of this war-beneath-a-war are the novel Birdsong by Sebastian Faulks and the Australian film Beneath Hill 60.

Now part of that underground battlefield is being studied by a team of British archaeologists. After detailed research in archives of several nations they’ve pinpointed a network of British and German tunnels under the French town of La Boisselle and have tracked down who fought there and when. They even know where some of these poor fellows got buried alive.

Right now the team is using ground-penetrating radar to map the tunnels and will being excavating in October. Some tunnels can still be entered while others are too unstable or have collapsed. Eventually the site will be opened up as a museum commemorating those who fought underneath the Western Front.

Mystery mound in England turns out to be ancient monument


England’s prehistoric landscape has a new addition.

Marlborough Mound in Wiltshire has long been a mystery. The flat-topped cone of earth looks like a smaller version of Silbury Hill, pictured here. The bigger mound was finished around 2300 BC at a time when Neolithic farmers were erecting stone circles such as Stonehenge and Avebury. Now archaeologists have taken samples from Marlborough Mound and carbon dated them to 2400 BC.

Carbon dating, which measures decaying carbon isotopes in organic matter, has a slight margin of error that increases the older the sample is. Thus Silbury Hill and Marlborough Mound may have been finished simultaneously, or at least in the same generation. The two mounds are only about 20 miles apart, a day’s walk for a Stone Age farmer or excited archaeologist.

The mound was reused several times. The Romans had a settlement next to it and the Normans built a castle on top of and around it in the late 11th or early 12th century. Early Norman castles were wooden palisades around an artificial mound. In this case their prehistoric predecessors saved them some work. The wooden walls were later replaced with stone ones but the castle has long since vanished. In the 17th century the mound was turned into a garden. The mound stands on the grounds of Marlborough College and is off-limits to visitors. Hopefully that will change now that its true importance is understood.

Skeletons at royal castle in Scotland killed in battle, experts say


Stirling Castle in Scotland was the scene of several brutal sieges and battles in its violent history. Now a new exhibition looks at the castle’s past and the grim discovery of several skeletons in the Royal Chapel showing signs of violent death.

One man had 44 skull fractures from repeated blows with a blunt object, and up to 60 more over the rest of his body. The Middle Ages were a pitiless time, and despite what modern romance novels say there wasn’t much chivalry. The skeleton of a woman had 10 fractures to her skull, resulting from two heavy blows. Neat, square holes through the top of her skull suggest she may then have fallen and been killed with a weapon such as a war hammer. At least five skeletons in the chapel showed signs of violent death. Carbon dating shows they died in several incidents between the 13th century and c.1450.

One of the skulls can be seen in this photo courtesy of Historic Scotland. Holding it is Dr. Jo Buckberry of Bradford University, who carried out the research on the skeletons.

The chapel was excavated as part of Historic Scotland’s restoration of the castle’s 16th century palace. The fact that the people were buried here indicates they were important.

One has been tentatively identified as Sir John de Stricheley, who died in 1341. Sir De Stricheley and the lady’s skeleton were featured last year on BBC2’s History Cold Case series.

Stirling Castle was an important castle on the boundary between Scotland and England and was besieged numerous times during the Wars of Scottish Independence (1296-1328 and 1332-1357). Several battles occurred nearby.

The exhibition, including facial reconstructions of Sir De Stricheley and the lady, will open June 4.

Robot discovers secret writing in Great Pyramid


The Great Pyramid of Cheops at Giza has always sparked the imagination. Among its many mysteries are four tiny passages running through the interior. The smallest are only eight inches square, far too small for a person to crawl through, so what were they for?

As you can see from the cutaway above, two of the tunnels angle up from the King’s Chamber to exit the pyramid. Some researchers believe these have astronomical alignments. Like with all ancient agricultural societies, observing the heavens was important to the Egyptians. The other two tunnels seem not to go anywhere. Some claim they lead to hidden chambers, or allowed the pharaoh’s soul to pass out of the tomb, but nobody really knows. Now a robot has added new pieces to the puzzle by going down one of these tunnels and filming it.

Robots in the pyramids are nothing new. Robotic exploration started in the 1990s, when remote-controlled cameras on wheels rolled up the two lower tunnels, only to find them blocked by strange stone “doors” decorated with a pair of copper pins. One of the doors had a small hole drilled in it, and a new robot with a camera on the end of a flexible cable looked on the other side.

What it found raises more questions than it answers. The secret door doesn’t seem to have any way to open, and on the other side of it are hieroglyphs. Egyptologists are hoping the hidden message will explain one of the pyramid’s greatest mysteries.

Why is there writing where nobody can read it? And why is the back of the door highly polished? There’s also a mason’s mark on the stone that the researchers are puzzling over. Egyptologists are busy trying to decipher the hieroglyphs and are planning more journeys for the intrepid robot. For more on the technology behind the discovery, check out this post on Dr. Zahi Hawass’ website.

These are good times for pyramid studies. A satellite has detected what could be seventeen lost pyramids, and last summer the pyramids of Abusir and Dahshur opened to the public.
