That the name survived at all is part of what makes the site quietly compelling. Sweathouses, known in Irish as tigh alluis, were small stone chambers used for therapeutic sweating, broadly comparable in function to a sauna. A fire would be lit inside, the embers raked out, and a person would crawl in and endure the heat, often as a treatment for rheumatism or other ailments. They are found in some number across counties Leitrim, Cavan, and Donegal, and Leitrim in particular has enough of them to support a dedicated recording project.

This particular example was reported in October 2021 by Aidan Harte, Project Co-ordinator of the Leitrim Sweathouse Project, though it had not yet been inspected at the time of reporting, and it does not appear on Ordnance Survey maps. What is known comes largely from the landowner, P. Reilly, whose family connection to the site runs deep enough that he wrote about it in 'The Sweathouse Field', an article published in the locally produced Drumgownagh School: Reunion and Heritage Book in 2013. That piece represents, for now, the most substantial account of a monument that official cartography never acknowledged and that the landscape has almost entirely absorbed.
