Beneath the lush peat of Scotland's Isle of Arran, a 5,000-year-old ritual circle has emerged, thanks to innovative geophysical scanning. This discovery reveals a ring of 12 underground pits, likely from the Neolithic or Bronze Age, without the disturbance of digging. The site adds a mysterious new chapter to the storied past of Machrie Moor, potentially indicating the presence of ancient ceremonial timber structures.
