Altar Stone, Central megalith at Stonehenge, England
The Altar Stone, a gray-green sandstone block measuring 5 meters in length, lies horizontally at the center of the stone circle formation.
Archaeological studies indicate the placement of this six-ton stone occurred during the second construction phase of Stonehenge between 2620 and 2480 BCE.
The name originated from architect Inigo Jones in 1620, who pondered whether the stone served ceremonial functions within the ancient structure.
The stone remains in a recumbent position with Stone 55, a sarsen megalith, positioned perpendicularly across its surface at the monument site.
Recent research from 2024 confirms the stone's origin in northeast Scotland's Orcadian Basin, marking a transport distance of 750 kilometers to Stonehenge.
