Archaeologists believe they have identified a much older and simpler predecessor to Stonehenge located about three miles (five kilometres) from the famous prehistoric monument in southern England.

The newly discovered site dates back approximately 5,000 years, making it around 500 years older than Stonehenge. Although little remains of the structure today, researchers uncovered two post holes that once held large wooden posts aligned with the sunrise and sunset during the summer and winter solstices, mirroring the astronomical orientation seen at Stonehenge.

Excavations also revealed pottery fragments, flint tools, and animal bones, indicating that prehistoric communities likely gathered at the site for ceremonies, feasts, or seasonal celebrations.

Phil Harding of Wessex Archaeology, who led the excavation, described the discovery as one of the most significant of his career. He explained that the post holes provide valuable insight into the beliefs and social practices of people living 5,000 years ago, suggesting they had a strong connection to celestial events and shared communal traditions.

Researchers believe the find could help improve understanding of how ceremonial monuments evolved in prehistoric Britain and may shed light on the cultural developments that eventually led to the construction of Stonehenge.

Further analysis is expected to determine the site’s full significance and its relationship to the wider prehistoric landscape surrounding Stonehenge, one of the world’s most iconic ancient monuments.
