The interior and the earthwork that defines it are entirely consumed by dense scrub, making it one of those sites that demands a certain kind of attention, the sort that looks past the surface tangle and asks what the ground beneath is actually doing.

A ringfort, or rath, is an enclosed farmstead of early medieval Ireland, typically circular or oval and defined by one or more earthen banks with an outer ditch. They were the standard unit of rural settlement for centuries, numbering in the tens of thousands across the country, though many have been levelled by agriculture or development. This example at Tullaha is oval in plan, measuring roughly twenty metres on its north-south axis and thirty metres east to west. The enclosing element takes the form of a scarped edge, essentially a cut or sloped face in the earth, rising to about 1.2 metres in height and around two metres wide. Running from the south-west around to the north-north-west is a fosse, the outer ditch that would once have reinforced the boundary; it is waterlogged, shallow at around 0.4 metres deep, and nearly three metres wide. Denis Power compiled the site record, uploaded in August 2011.

Access is not straightforward, and the notes make no bones about that. The northern boundary runs along a public road, which at least provides a reference point for orientation, while the western edge is defined by a stream. The scrub overgrowth covers both the interior and the enclosing earthwork completely, so any sense of the fort's shape will come from careful attention to subtle changes in ground level rather than from clear visual features. The waterlogged fosse to the south-west and north-north-west may be easier to read in drier months when the vegetation is somewhat less assertive, though the waterlogging suggests this is a persistently damp corner of ground regardless of season. Anyone visiting should expect to work for their reading of the landscape.
