Team discovers circular structure near Stonehenge

— Scientists scouring the area around Stonehenge said Thursday that they have uncovered a circular structure only a few hundred yards from the world-famous monument.

There’s some debate about what exactly has been found. The survey team that uncovered the structure said it could be the foundation for a circle of freestanding pieces of timber, a wooden version of Stonehenge.

But Tim Darvill, a professor of archaeology at Bournemouth University in southern England, expressed skepticism, saying he believed it was more likely a barrow, or prehistoric tomb.

The stonehenge that is visible today is thought to have been completed about 3,500 years ago, although the first earthwork henge on the site was probably built more than 5,000 years ago.

Although antiquarians have been poking around the area since the 18th century, excavations are now tightly restricted.

So archaeologists have been scanning the surrounding fields and pastures with magnetic and radar sensors pulled across the grass by tractors or quad bikes.

The new structure was found when scans identified a cluster of deep pits surrounded by a ring of smaller holes a little more than half a mile from Stonehenge and within sight of its famous standing stones.

University of Birmingham archaeologist Henry Chapman said he was convinced that the small holes were used to secure a circle of wooden poles which stood “possibly 3 or more meters [10 or more feet] high.”

The timber henge - a name given to prehistoric monuments surrounded by a circular ditch - would have been constructed and modified at the same time as its more famous relative, and probably had some allied ceremonial or religious function, Chapman said in a telephone interview from Stonehenge.

Exactly what kind of ceremonies those were is unclear.

Darvill said the circle was one of an expanding number of discoveries being made around Stonehenge that “really shows how much there is still to learn and how extensive the site really was.”

“In its day Stonehenge was at the center of the largest ceremonial center in Europe,” he said.

The new henge joins a growing complex of tombs and mysterious Neolithic structures found across the area.

The closest equivalent is probably the nearby Woodhenge, a monument oncecomposed of six rings of wooden posts enclosed by an earth embankment. Excavations there in the 1970s revealed the body of child whose skull had been split buried at the center of the henge, hinting at the possibility of human sacrifice.

A stone’s throw from the newly found henge is a formation known as the Cursus, a 1.8-mile-long earthwork whose purpose remains unknown. Also nearby is a puzzling chunk of land known as the Northern Kite Enclosure; Bronze Age farmers seem to have avoided cultivating crops there, although no one is quite sure why.

The whole area around Stonehenge is dotted with prehistoric cemeteries, some of which predate the monument, and new discoveries are made occasionally.

Last year, researchers said they had found a small circle of stones on the banks of the nearby River Avon. Experts speculated the stone circle, dubbed “Bluehenge” because it was built with bluestones, may have served as the starting point of a processional walk that began at the river and ended at Stonehenge.

Chapman’s team is still in the early stages of its work, having surveyed only about 1.5 square miles of the 6 square miles it plans to map eventually.

The survey is being led by the University of Birmingham and the Austria-based Ludwig Boltzmann Institute for Archaeological Prospection and Virtual Archaeology, with support from other institutions and researchers from Germany, Norway and Sweden.

Henges of various descriptions exist throughout Britain, from the Standing Stones o’ Stenness on the northern island of Orkney to the Maumbury Rings in southern England county of Dorset.

Stonehenge, a World Heritage site, remains the bestknown.
