One of the most fascinating archaeological mystery is the discovery of the so-called Cochno stone.
Discovered in 1887 by the Rev. James Harvey, the ancient stone measures 13 meters by 7.9, and features around 90 intricate carvings—considered as one of the finest sets of petroglyphs in Scotland—which according to many researchers represent a cosmic map, detailing planets and stars.
After its discovery, in 1965 archaeologist Ludovic Maclellan Mann decided to bury the massive slab under several feet of soil to protect it from further damage and to prevent people from adding their own carvings onto it.
