What survives at Clogh is a subcircular rath, a type of enclosed settlement once numbering in the tens of thousands across Ireland, typically used by a farming family of some local standing during the early medieval period, roughly between the fifth and twelfth centuries. This one measures approximately 33 metres north to south and 28 metres east to west, making it a modest but respectable example of its kind.

The enclosure is defined in an uneven way, which is part of what makes it worth a second look. Along the southwestern to northwestern arc, a proper earthen bank still survives, the kind that would once have supported a timber palisade or a thorn hedge to keep livestock in and unwanted visitors out. Elsewhere, the boundary has been reduced to a scarp, a sloped edge in the terrain rather than a built-up wall, suggesting that centuries of ploughing, grazing, and weathering have gradually worn the original earthwork down on certain sides. Circling the entire monument, however, is a berm, a flat ledge or shelf of ground set between the inner enclosure and any outer ditch, which in this case helps define the full extent of the site even where the bank itself has diminished. The condition is described as fair, which in archaeological terms means enough remains to read the form clearly, even if the monument is no longer intact.
