Not far from Stonehenge, a worldwide wonder, is another structure that appears quite similar in its construction, only larger and older.

According to The Guardian, the monument unofficially dubbed "Superhenge" is made up of about 90 stones standing upright forming a massive "C" when seen from above. Vince Gaffney, an archaeologist at Bradford University, lead the Stonehenge Hidden Landscape project that made the discovery.

"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," he told The Guardian. "This is archaeology on steroids.

"We presume it to be a ritual arena of some sort."

"Our high-resolution ground penetrating radar data has revealed an amazing row of up to 90 standing stones, a number of which have survived after being pushed over, and a massive bank placed over the stones," Wolfgang Neubauer, director of the Ludwig Boltzmann Institute for Archaeological Prospection and Virtual Archaeology, told CNN. "In the east up to 30 stones, measuring up to size of 4.5 by 1.5 by 1 meters (14.7 by 5 by 3.3 feet), have survived below the bank whereas elsewhere the stones are fragmentary or represented by massive foundation pits."

"Superhenge" is estimated to be 4,500 years old, which would outdate Stonehenge.

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