John Wilmet, 78 years old, began by telling me the following tale about an allee couvert: “William Murphy, who married my sister, once went to the pisky-house at Bosahan with a surveyor and the two of them heard such unearthly noises in it that they came running home in great excitement, saying they had heard the piskies.”
This is surely the place to which this anecdote (from Evans Wentz’s ‘Fairy Faith in Celtic Countries’ 1911) refers, as if you look on the map it is between Bosahan farm and Bosahan quarry.
