What remains of Teampall Éinne, dedicated to Saint Enda, amounts to a roofless shell measuring roughly six metres by four, but within that modest footprint several layers of religious activity can still be read in the stonework and the ground itself. The west wall retains a trabeate doorway, meaning one formed with a flat stone lintel rather than an arch, a feature typical of early Irish ecclesiastical building. At the east end, lower and less legible foundations mark where a chancel was added at some later point, extending the original structure by a further five metres or so. The two builds sit awkwardly together, as though the site kept attracting use long after anyone had agreed on a plan.

The references to the site go back at least to George Henry Kinahan's observations in 1868, and Lord Killanin noted it in 1947 and again in a later county guide co-authored with Michael Duignan. The oratory's name connects it to Saint Enda of Aran, one of the more prominent figures in early Irish monasticism, though the small scale of what survives here suggests a modest foundation rather than a major centre. A low curving scarp, traceable only to the north-east of the oratory, may represent the remnant of an early ecclesiastical enclosure, the kind of boundary that would have defined the sacred precinct of an early medieval religious community. The cluster of features nearby adds to the sense of accumulated devotion: a holy well and a bullaun stone, which is a boulder with one or more cup-shaped depressions used in early Christian and possibly pre-Christian ritual, lie to the north-west, and a cillin, a burial ground associated with unbaptised children, sits immediately to the south-west.
