The Rugglestone, The Ruggle Stone
In 'High Dartmoor' Eric Hemery (1983) describes Rugglestone Rock as a tor and at one time the logan stone here could be rocked. Difficult to access from the east through bog and thick vegetation the site is better reached from the direction of Venton below.
And in 'Guide to Dartmoor' William Crossing tells us of the tor: "...and from there the rambler will strike W. down the hill to the Ruggle Stone, 1/2 m. distant. When we draw near the walls of the enclosures we bear a little to the R., and speedily arrive at that object. The Ruggle Stone is a huge mass of granite resting on the rocks in such a manner as to slightly log, though it used to be said that it could only be set in motion with the aid of the church key."
"It is about 22 feet in length and 16 feet wide. Close to it is another "logging" stone, but one of a different character. It resembles a large slab, and is not more than half the length of the other. The weight of the larger rock has been computed to be about 115 tons."
