These kinds of sites, sometimes the remains of a single dry-stone or earthen-walled dwelling, can date from anywhere between the early medieval period and the post-medieval centuries of rural hardship. Without further detail it is difficult to say more about what precisely survives at ground level, whether a low circular wall, a scraped-out platform, or simply a soil anomaly that rewards a closer look.

Hut sites in the west of Ireland are frequently associated with the seasonal practice of booleyingthe movement of people and livestock to upland or marginal grazing in summer months, with temporary shelters built or reused each season. In other cases they represent more permanent, if modest, habitation, the kind of one-roomed dwelling common during the centuries before and after the Great Famine. Rossbeg, like much of this part of Mayo, would have carried a dense population before the 1840s, and the traces of that occupation linger in the form of earthworks, field boundaries, and structures like this one, half-absorbed into the bog or grass.
