It sits in that curious category of Irish archaeological sites that are known to exist, are protected in principle, but remain effectively invisible to anyone trying to understand what they are actually looking at.

Enclosures are among the most common monument types in the Irish landscape. The term covers a wide range of features, from the circular earthen banks of a ringfort, which would have enclosed a farmstead during the early medieval period, to later field boundaries and enclosures of uncertain date and function. Without more detail about Ballybroghan specifically, it is not possible to say which kind this is, when it was constructed, or by whom. What can be said is that Clare is a county whose landscape holds an extraordinary density of such features, many of them still visible as low earthworks or crop marks, and that Ballybroghan, as a placename, suggests a townland with its own long history of habitation and land use. The Irish "baile" points to a settlement place, though placename interpretation without supporting evidence is its own kind of speculation.
