These earthwork enclosures, known as raths, were typically built during the early medieval period as farmstead boundaries, defined by a raised bank of earth and an outer ditch called a fosse. Thousands survive across Ireland in varying states of repair, but this one sits at the less legible end of that spectrum.

The rath at Ballynacurragh is oval in plan, measuring roughly 25 metres on its northeast to southwest axis and about 20 metres across from northwest to southeast. What once would have been a clearly defined enclosure, with a bank perhaps used to pen livestock or mark a family's land, is now difficult to read on the ground. The earthen bank and its accompanying external fosse are still technically there, but heavy overgrowth has made the form hard to distinguish from the surrounding pastureland. Sites like this are often passed over precisely because they demand a certain patience; there is nothing immediately arresting about a mounded field boundary half-consumed by bramble and grass.

The slope faces north, which means the site receives less direct light than the surrounding terrain, a small detail that may partly explain why the vegetation here is so persistent. There are no particular visitor facilities or formal access points associated with the site, and anyone attempting to locate it should expect to work at reading the contours of the land rather than following any obvious markers.
