What remains is a rath, a type of ringfort built during the early medieval period, roughly between the fifth and twelfth centuries, that once served as an enclosed farmstead for a family of some local standing. This one measures about 44.5 metres in diameter, defined by a bank and an external fosse, the shallow ditch dug to provide material for the bank itself, though both have been considerably reduced over time.

The bank survives in its most legible form on the western side, where the fosse is still traceable. Elsewhere, several breaches interrupt the circuit, and these appear to be modern intrusions rather than original entrances or the result of gradual decay alone. A second ringfort lies approximately 180 metres to the northwest, which is not unusual in the Irish landscape; paired or clustered ringforts sometimes reflect related family groups or successive occupation of the same territory across generations, though what precise connection existed between these two examples at Carrowgorm is not recorded. With somewhere between 40,000 and 50,000 ringforts once dotting the Irish countryside, they represent the most common surviving monument type in Ireland, yet the majority, like this one, are worn to near-invisibility, their social and agricultural significance easy to underestimate from what little earthwork remains.
