That a later agricultural structure was cut directly into its scarp says something quietly telling about how the past gets absorbed into the practical needs of the present.

Limekilns were once commonplace across the Irish countryside, used to burn limestone at high temperatures and produce quicklime for spreading on acidic fields or for making mortar. They were typically simple stone-lined chambers set into a slope, which allowed the kiln to be loaded from above and the burnt lime to be drawn out at the bottom. The choice of site here was almost certainly opportunistic: the existing earthen bank of the rath offered a ready-made gradient, saving the effort of cutting into flat ground. The rath itself, a category of monument that numbers in the thousands across Ireland, predates the kiln by many centuries, though exactly when either structure was built or modified is not recorded.
