(BBC News) Archaeologists believe they have discovered an earlier, much simpler version of Stonehenge about 5 kilometres away from the prehistoric monument.
All that remains of the older structure is two holes in the ground, but the team says they held wooden posts that lined up with the Sun on the summer and winter solstices – the longest and shortest days of the year – in the same way as Stonehenge.
The site has been dated to about 5,000 years old, which predates Stonehenge by 500 years.
Artifacts were also found at the site, including pottery, flint tools and animal bone, suggesting prehistoric people held gatherings there.
Phil Harding, from Wessex Archaeology, who led the excavation, said it was one of the best finds of his long career.
“Two post pits tell me [much] more about the people 5,000 years ago,” he said.
“This tells me about the whole community, this tells me about how they were thinking, how they were behaving, how they were revering the heavens.”
The huge stones at Stonehenge are precisely placed to line up with the Sun.
If you stand in middle of the circle at sunrise on the summer solstice, you will see the Sun come up over a stone called the heel stone to the northeast of the circle.
On midwinter, if standing in the centre of the circle, you would see the sun set over an altar stone to the southwest of the site.
The structure, discovered in the village of Bulford, was a much more simple construction made up of just two wooden posts, which have long since rotted away.
They were positioned 120 metres apart and estimated to be 2-4 metres high.
When Harding uncovered the intriguing holes, he noticed that they seemed to line up with the Sun, just like Stonehenge located a few miles away.
“I got my pencil and ruler, and I joined them up, and I was aware that they were kind of pointing in the general direction of the sunrise on midsummer,” he said.
The traces of the earlier structure were found a decade ago in Bulford when the ground was cleared for new army housing.
But it is only now that a detailed analysis of the alignment has been carried out, which involved turning back the celestial clock.
