It rises four metres from the surrounding ground, its sides steep enough to slow your footing, its flat-ish top just wide enough to give a clear view outward. That view, though, is not what it once was. Where an extensive low-lying plain would once have stretched away to the horizon, there are now housing estates, the ordinary suburban spread of modern Dublin pressing right up to the convent walls.

The mound is roughly circular, measuring around fifteen metres in diameter, and its form, a round-topped earthwork with pronounced steep sides, is consistent with the kind of early medieval monument found scattered across the Irish landscape, though no specific date or origin is recorded for this one. Such mounds served various purposes in early Irish society, from burial to inauguration to boundary-marking, and their presence on land later absorbed by religious institutions is not unusual. The site now sits within the grounds of a convent that was formerly the Claremont Institution, a detail that gestures at the layered uses this land has seen over the centuries. The western and north-western sides of the mound have been damaged at some point, and the whole structure is heavily overgrown with thorns and sycamores, giving it the slightly unkempt, half-forgotten quality that tends to settle over earthworks when nobody is quite sure what to do with them.

Access to the mound is contingent on access to the convent grounds, which are private. The site is not a public amenity in any straightforward sense, and anyone hoping to see it should make enquiries accordingly. If you do get close, the overgrowth means the mound is easier to sense than to see clearly from ground level; the steep sides become apparent only when you are standing at the base. The damage to the western and north-western edges is worth noting as a reminder of how quietly these earthworks erode, whether through development, landscaping, or simple neglect, before anyone has thought to record exactly what they are.
