The recent discovery of a massive Neolithic stone monument in Stonehenge has been described by researchers as "archeology on steroids."

Believed to be hauled into position more than 4500 years ago, the massive stone monument was discovered by archeologists along a bank two miles from Stonehenge, reported the Guardian.

"What we are starting to see is the largest surviving stone monument, preserved underneath a bank, that has ever been discovered in Britain and possibly in Europe," said Vince Gaffney, Bradford University who leads the Stonehenge archeologist who is leading the Hidden Landscape project.

Using ground-penetrating radar, researchers were able to image 30 intact stones measuring up to 4.5m tall, while the fragments of 60 more buried stones revealed the monument's full extent.

The massive stones formed part of a C-shaped Neolithic arena that bordered a dry valley and directly faced the river Avon.

They seem to have been joined with a chalk ridge that was cut into in order to accentuate the natural border.

The discovery of the monument at Durrington Walls puts forward the idea that buildings were modified and later recycled since the first stones in Stonehenge were laid around 3100BC.

"Everything written previously about the Stonehenge landscape and the ancient monuments within it will need to be rewritten," said archeologist Paul Garwood, who is also a lead historian on the project at the University of Birmingham.

Nick Snashall, a National Trust archaeologist for the Avebury and Stonehenge world heritage site, said, "These latest results have produced tantalising evidence of what lies beneath the ancient earthworks at Durrington Walls.

"The presence of what appear to be stones, surrounding the site of one of the largest Neolithic settlements in Europe, adds a whole new chapter to the Stonehenge story," he added.

The Stonehenge Hidden Landscape project has changed the way archaeologists view the sprawling, ancient site, which is over four square miles of Salisbury Plain in Wiltshire.

Meanwhile, historian Phil McHahon re-echoed the importance of the latest discovery at Stonehenge and its impact on the work being carried out by archeologists at the site, according to i09.

"This latest work has given us intriguing evidence for previously unknown features buried beneath the banks of the massive henge monument at Durrington Walls.

"The possibility that these features are stones raises fascinating questions about the history and development of this monument, and its relationship to the hugely important Neolithic settlement contained within it," he added.

The Stonehenge discovery shows that there is still much to learn about the planet's history.
