Under an oak in Shebbear village square is a big conglomerate boulder. Every 5th of November, the bellringers lever up the stone and turn it over, then ring a peal of bells. Apparently the devil lives under the stone, and this stops him wreaking havoc for the next year. There is another stone about 750m north too but it doesn’t get a name.
The custom has nothing to do with increasing the trade in the nearby ‘Devil’s Stone Inn’.
Also it seems that the inn is haunted:

according to Craig Tennant~Smith. But whether that has anything to do with the influence of the stone, who can say...
