Archaeologists revealed Thursday that they have discovered a structure near the prehistoric stone circle of Stonehenge in southern England that may have served as a “prototype” for the 5,000-year-old Neolithic monument.
A team from the British firm Wessex Archaeology said the structure would have consisted of two wooden poles 120 meters (394 feet) apart and aligned to point directly at the rising sun during the summer solstice and the setting sun at the winter solstice.
Researchers said the discovery predated Stonehenge by around 500 years.
The team was led by archaeologist Phil Harding, who is well known in the U.K. through his many years of excavations for Channel 4 TV series “Time Team.”
Harding, 76, said the site, which also turned up a treasure trove of finds including pottery, animal bones and a rare disc-shaped knife, was likely to have been a focus for major religious gatherings.
“Opportunities like this probably only come once in a career, in a lifetime,” Harding said. “I’m probably towards the end of my career now, but thank God I’m still in archaeology long enough to be part of this discovery, because it’s certainly the highlight of my career.”
The findings were released ahead of the summer solstice, which falls this year on Sunday, when thousands head to Stonehenge each year to celebrate the longest day of the year in the Northern Hemisphere.
Stonehenge is a symbol of British culture and history and remains one of the country’s biggest tourist draws. The World Heritage Site was built on the flat lands of Salisbury Plain in stages starting 5,000 years ago, with the unique stone circle erected in the late Neolithic period about 2,500 B.C.
The site’s meaning has been the subject of vigorous debate. The most generally accepted interpretation is that it was a temple aligned with movements of the sun — lining up perfectly with the summer and winter solstices.
Researchers who found the structure near Stonehenge carried out the dig at Bulford, 5 kilometers (3.1 miles) from the main stone circle, as part of archaeological work to support the British defense ministry’s program to accommodate troops who have been withdrawn in recent years from Germany, where the army had a big footprint for decades. The area around Stonehenge is one of the largest military training grounds and in the U.K. and Bulford is home to a barracks.
