Outside the enclosure to the north, a rectangular platform carries a leacht, a type of low commemorative or penitential stone cairn, and another cross-slab. The site looks out over the mouth of Kenmare Bay towards the Beara Peninsula, and the whole ensemble at Cill Rialaigh has the quality of a place that was never entirely abandoned, even as the centuries moved on around it.

One of the rectangular buildings within the cashel is a notably modest structure. Its internal dimensions measure 5.3 metres north-west to south-east and 2.7 metres north-east to south-west, with walls surviving only one or two courses high and roughly 0.7 metres wide. A possible entrance gap sits in the north-west end-wall. Archaeologists have noted that it may be of relatively recent date, which introduces a quietly interesting complication to a site otherwise associated with early Christian activity. Cill Rialaigh functioned as a ceallúnach, a burial ground used by communities outside the formal parish system, sometimes for unbaptised children or others excluded from consecrated ground, and this use continued into the nineteenth century. A holy well lies approximately ninety metres to the south-west, adding another layer to what is clearly a site where religious and communal life persisted across a very long span of time.

The setting rewards careful attention. The cashel wall remains strong, and several of the enclosed structures are legible at ground level even where walls survive only at foundation height. The cross-slabs and the covered passage are the kinds of features that can be easy to walk past without registering their significance; slowing down and looking at the relationship between the different elements, inside and outside the enclosure, gives a clearer sense of how the site was organised and used across different periods.
