The earthen bank that once defined it has been so thoroughly reduced by centuries of agriculture and weather that its highest point barely reaches seventy centimetres above the surrounding ground. What remains is a broad, low ring of earth, its base spreading between eight and thirteen metres wide in places, enclosing a sub-circular area roughly twenty-three metres across north to south and thirty metres east to west. The dimensions suggest something that was once substantial; the current condition suggests a long, slow erasure.

This is a univallate rath, meaning a ringfort enclosed by a single bank and ditch, the most common type of early medieval settlement in Ireland. Thousands of them survive across the country in varying states of preservation, built roughly between the fifth and twelfth centuries as enclosed farmsteads for free farming families. The earthen bank, originally much higher and often accompanied by an external ditch, would have defined a household's territory and provided a degree of protection for people and livestock alike. The Finuge example follows the standard form, but its advanced levelling places it at the more fragile end of the survival spectrum. It sits to the north-east of another recorded site in the same area, suggesting this part of north Kerry was reasonably well settled during the early medieval period.
