Archaeologists in southern England have discovered a prehistoric structure near Stonehenge that may have served as an early “prototype” for the famous stone circle.

The site, located near Bulford, is believed to predate Stonehenge by about 500 years and featured wooden posts aligned with the sun’s movements during the solstices.

Excavations uncovered pottery, animal bones, and rare artifacts, suggesting it was a major ceremonial gathering place.

Researchers say the discovery supports the idea that the area had long-standing solar and religious significance before Stonehenge was built, the AP has reported.

The findings add to ongoing debates about Stonehenge’s purpose as crowds continue to gather each year to mark the summer solstice.
