A team of archaeologists has uncovered what appears to be a much older, simpler ancestor of Stonehenge just three miles from the world-famous Wiltshire monument, potentially reshaping our understanding of why our prehistoric ancestors were so fixated on the movements of the Sun.
The discovery, made in the village of Bulford, consists of two holes that once held wooden posts positioned 120 metres apart. While the timber has long since rotted away, the alignment of these post pits points directly toward the summer and winter solstices – the longest and shortest days of the year – in exactly the same way as the towering stone circle that now draws thousands of visitors annually.
Radiocarbon dating has confirmed the site dates back roughly 5,000 years, making it half a millennium older than the earliest phase of construction at Stonehenge itself.
Phil Harding from Wessex Archaeology, who led the excavation, described the find as one of the most significant of his lengthy career. “Two post pits tell me 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 discovery came about a decade ago when the ground was cleared for new army housing. However, it is only now that detailed analysis of the celestial alignment has been completed – a process that involved reconstructing what the night sky would have looked like five millennia ago.
“We basically need to reconstruct the sky, what it looked like exactly 5,000 years ago, where the Sun was rising and what time it was rising in those places,” explained Dr Fabio Silva, an archaeoastronomer from Bournemouth University and the Skyscape Academy.
When Harding first uncovered the intriguing holes, he noticed they seemed to line up with the Sun, much like Stonehenge situated 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 recalled.
The breakthrough came when account was taken of the width of the original posts. “Then the alignment is exactly, exactly right,” Silva confirmed. “It’s accurately aligned to summer solstice sunrise and winter solstice sunset.”
The posts themselves would have stood between two and four metres high, creating a modest but deliberate framework for tracking celestial movements.
Surrounding the two main post pits, the excavation team uncovered dozens of additional holes containing a treasure trove of artefacts: an antler that would have been used for digging, intricately carved animal bones, and fragments of finely decorated pottery. Flint tools were also recovered, including a rare Neolithic knife that had been shaped into a discoidal – circular – form.
Harding singled out this discovery. “It was, I think, our star find,” he said. “What is so special about it is the workmanship that’s gone into it. That is the work of real craftsmanship.”
The knife was found standing upright, suggesting it may have been deliberately placed rather than simply discarded. Harding speculated whether its distinctive shape held symbolic significance. “Maybe that discoidal shape is some sort of reference to the Sun, who knows?”
The presence of these items points to gatherings of prehistoric people at the site – perhaps seasonal feasts or ceremonies tied to the solar calendar.
Dr Jennifer Wexler, curator of history at English Heritage, believes the discovery has profound implications for our understanding of Stonehenge. “The discovery of Bulford actually suggests that maybe the people who built the first stages of Stonehenge were based or living there, or at least gathering seasonally to do the construction work at Stonehenge,” she said.
The monument at Bulford dates to the same period as the earliest earthworks at Stonehenge, half a millennium before the iconic bluestones and sarsens were positioned.
So why were these ancient communities so captivated by the Sun? “The people who built Stonehenge and the people who were at Bulford were early farmers, and their livelihoods really were connected to the seasons and the Sun doing its job,” Wexler explained.
Today, the summer solstice draws the biggest crowds to Stonehenge, with thousands gathering to witness sunrise at the monument. Yet 5,000 years ago, the winter solstice may have held even greater importance.
“Winter might have been particularly important because it’s a time of year when the light is literally dying, and maybe you need to do something to evoke that return or mark it, because then it’s a return of the spring, when hopefully your crops and your animals will thrive,” Wexler said.
The huge stones at Stonehenge remain precisely positioned to align with solar events. Standing in the centre of the circle at summer solstice sunrise, the Sun emerges over the heel stone to the north east. At midwinter, viewers witness the Sun setting over the altar stone to the south west.
Why it Matters
This discovery fundamentally challenges the notion that Stonehenge emerged in isolation as some unique astronomical monument. Instead, it suggests a widespread tradition of solar observation among Neolithic communities across the Salisbury Plain, with Bulford representing a likely precursor – and possibly a gathering place for those who would later construct the greater monument. The find demonstrates that Britain’s prehistoric inhabitants possessed sophisticated knowledge of celestial movements and organised their spiritual and communal life around them. As climate concerns intensify modern debates about humanity’s relationship with the Sun, this 5,000-year-old testimony reminds us that our ancestors already understood what was at stake.
