Dating back to the 16th century, Greyfriars Kirkyard is infamous as one of Scotland’s most haunted graveyards. The site is linked to the restless spirit of Sir George Mackenzie, nicknamed “Bloody Mackenzie,” whose mausoleum is said to unleash violent poltergeist activity on unwary visitors. Reports of scratches, bruises, and sudden fainting fits have made the cemetery a hotspot for ghost tours.
