A groundbreaking study published in the journal Nature has revealed that the Altar Stone, the largest among the inner circle of "bluestones" at Stonehenge, originated from the north east corner of Scotland. This discovery contradicts previous beliefs that the stone was sourced from western Wales and transported approximately 200km to its current location on Salisbury Plain in Wiltshire, England. The revelation is based on a detailed analysis of the stone's chemical composition.
