The six-inch maps of both 1837 and 1913 pass over it entirely, which is itself a small curiosity: by the earlier date, the Survey's surveyors were generally thorough, and an omission like this hints at a structure that was already a relic, already sinking back into the hillside, by the time anyone thought to record the landscape formally.

The structure is a booley hut, a type of seasonal shelter associated with the old Irish practice of booleying, or buaile, in which farming families would move their cattle to upland grazing through the summer months and live close by in temporary accommodation. The word comes from the Irish for a milking place or summer pasture, and these huts were never meant to last; they were built quickly, occupied briefly, and left behind when the season turned. The Tormore example dates to after 1700 and is built in drystone random rubble, that is, stones laid without mortar and without any particular attempt to sort them by size or shape. What remains is the footprint of a rectangular building running east to west, roughly six metres long and just under four metres wide, with wall footings surviving to a maximum height of about forty centimetres. The entrance has been lost entirely. About four metres to the north-north-east, a relic field system survives alongside it, a trace of the small enclosures that would have kept cattle near the hut during those summer stays.

The site sits on a slight south-west-facing slope at the base of the hollow, with open views stretching to the south-east, south, and south-west, though higher ground closes off the horizon in other directions. It is the kind of place that rewards patience with the landscape: the stones are low and easily missed, but the setting makes the logic of seasonal life here legible. The hollow would have offered some shelter; the views would have let a herder keep watch.
