The monument comprises a small defended enclosure or rath, which probably dates to the Iron Age period (800 BC - 43 AD). Usually enclosed by a bank and ditch, raths often contsin evidence of intensive occupation. Plumstone Rath is defended by a bank which rises 4ft above the interior and 10ft above the exterior. There is a rectangular annexe on the south, the banks of which are 3ft on inner and 10ft on the outer side.

The monument is of national importance for its potential to enhance our knowledge of Iron Age settlement and social organisation. The monument forms an important element within the wider later prehistoric landscape. The structure itself may be expected to contain archaeological information in regard to chronology, building techniques and functional detail.

The scheduled area comprises the remains described and areas around them within which related evidence may be expected to survive.
