The Shed Stone
The Dodder flows along the eastern boundary of the demesne where it is joined by a small stream coming down from the Featherbed Bog. On the northern bank of this stream, at a point 300 yards up from the Dodder, is a large rock raised up on three smaller ones, known locally as the Shed Stone and said to mark the position of buried treasure. (MacNeill and Dix. "Dolmen at Glenasmole", J.R.S.A.I. 1926, p. 122-123) Although this has the general appearance of a prehistoric dolmen or portal tomb, it is obvious on close examination that the supporting stones are actually three pieces of one stone which must have been split by the weight of the larger one above. These fragments are not placed to form a chamber or enclosure which is one of the chief characteristics of a prehistoric burial place. It would appear therefore that the unusual arrangement of these stones is entirely fortuitous. The height is about 4 feet.
