Càrn na Marbh (meaning "mound" or "cairn of the dead") is a re-used Bronze Age tumulus, located in Fortingall in Perthshire, Scotland.
A tablet on the stone is inscribed with the words: “Here lie the victims of the Great Plague of the 14th Century, taken here on a sledge drawn by a white horse led by an old woman.”Local legend says it was the focal point of an ancient Samhain (Halloween) festival.
[2] As the fire began to wane, some of the younger boys took burning embers from the flames and ran throughout the field with them, finally throwing them into the air and dancing over them as they lay glowing on the ground.
When the last embers were showing, the boys would have a leaping competition across the remains of the fire, reminiscent of the Beltane festival.
Place-name and archaeological evidence hint at an Iron Age cult centre at Fortingall which may have had this ancient tree as its focus.
