That small cartographic confusion is, in its way, more interesting than either feature alone.

The first edition of the Ordnance Survey six-inch map marked the site as a large sand pit, suggesting some form of extraction, most likely a quarry for sand or loose material. By the time of the 1898 resurvey, the pit had disappeared from the map entirely, replaced by the name "Fairy House" written in Gothic script, the lettering style OS cartographers typically reserved for antiquities and places of folkloric or historical note. The problem is that "Fairy House" almost certainly refers to a building situated roughly 190 metres to the south-east, a separate structure recorded on the earlier map. The Gothic label appears to have drifted, landing on the wrong spot and quietly transforming a workaday sand pit into something that sounds considerably more atmospheric. Whether the quarry was simply exhausted and forgotten by 1898, or whether the two features became conflated during the resurvey process, is difficult to say without visiting the ground itself.
