An enclosure in this context typically refers to a defined area bounded by an earthen bank, a fosse, or a combination of both, ranging in purpose from early medieval settlement and farming to ritual use. They are among the most common monument types in Ireland, yet each one carries its own unresolved questions about who built it, when, and why.

Glanlarehan sits in a county dense with prehistoric and early medieval remains, where the land has been worked and marked for thousands of years. Without further detail currently available for this particular site, its age, dimensions, and character remain open questions. It may be a modest ringfort-type enclosure of the early medieval period, the kind of farmstead that once housed a family and their livestock behind a raised bank for security and demarcation, or it could belong to an entirely different period and function. Kerry's archaeology runs deep, and even unassuming field boundaries can conceal significant histories.
