It had not gone anywhere, of course, but its gradual absorption into the surrounding boggy fieldscape had apparently made it difficult to render as a distinct feature. The locals, however, kept their own record: the waterlogged ground it occupies is still known as the fort field, a piece of placename memory that has outlasted the cartographers.

Ringforts, known in Irish as raths, were typically enclosed farmsteads of the early medieval period, their occupants protected by one or more circular earthen banks and external ditches. The Aghamore example measures roughly 31 metres across its internal diameter, a middling size for the type. What survives today is a semi-circular form rather than a complete ring; a fieldbank running north to south has cut into the eastern side, leaving the enclosure defined on its northern, southern, and eastern edges by modern field boundaries rather than original earthworks. To the northwest, west, and southwest, a faint trace of the exterior fosse, the outer ditch, can still be read in the ground. Where it is visible, the fosse is wet and roughly 2.8 metres wide, sitting about 0.6 metres below the level of the surrounding land. The enclosing bank rises 1.2 metres on its outer face, though only half to just under a metre above the interior, suggesting considerable silting and settling over the centuries. The site was recorded in detail by C. Toal as part of the North Kerry Archaeological Survey, published in 1995.

The boggy character of the field makes the fosse persistently wet, which is part of why its outline remains legible even where the bank itself has been reduced. Anyone approaching the site should expect soft ground, and the semi-circular earthwork is best appreciated by moving around its northern and western arc, where the relationship between the surviving bank and the waterlogged ditch is most apparent.
