Mary King's Close is a historic close located under the Edinburgh City Chambers building on the Royal Mile, in the historic Old Town area of Edinburgh, Scotland.
[3] The area became shrouded in myths and urban legends; tales of hauntings and murders abounded.
[6] Mary King's Close has had a reputation for hauntings since at least the 17th century, with several paranormal investigations taking place.
It has been pointed out that this particular Close ran the nearest of any to the old Nor Loch, a stagnant and highly polluted marsh; biogas escaping into the close and creating eerie lights may have been the cause for these rumours of spirit hauntings.
