The structure, around eight metres in diameter, is the kind of thing that can pass for centuries without formal notice, known perhaps to local farmers but not to any official record. It was only through satellite imagery captured between 2011 and 2013 that its outline became clearly legible to outside eyes.

The site was identified and reported to the National Monuments Service by Ros Ó Maoldúin, an instance of the kind of careful, patient observation that quietly expands our picture of how densely Ireland was once occupied. Hut sites of this general type, roughly circular enclosures built from stone or earth, appear across the Irish landscape in varying states of preservation, and can date from anywhere between the Bronze Age and the early medieval period. Without excavation, pinning down the age of any individual example is difficult. What the Lismacsheedy site offers is less a resolved story than an outline waiting to be read, a circle on a hillside that is older than anything written about it.
