The one at Bawnaglanna, in County Kerry, sits in this category, a rath whose circular earthwork, the defining feature of this type of enclosure, would originally have enclosed a farmstead during the early medieval period, roughly between the fifth and twelfth centuries. A rath, to distinguish it from a cashel, uses raised earthen banks rather than stone walls to define its boundary, and these structures were typically home to a single farming family of some social standing.

Bawnaglanna itself is a townland name with the feel of the landscape worked into it, and Kerry contains a remarkable density of such monuments, a reflection of the region's long agricultural history and the relative durability of earthen enclosures in its terrain. Beyond its classification and location, the documented record for this particular site currently offers little to work with, and what detailed history it carries, its original extent, any finds associated with it, or evidence of internal features, remains to be properly examined and published. That silence is itself a reminder of how much of Ireland's early medieval landscape is still in the process of being fully recorded, piece by piece.
