The fact that it survives at all in fair condition is itself worth pausing over; many comparable monuments have been ploughed out or built over, leaving little more than a crop mark.

This is a rath, the most common type of early medieval enclosed settlement in Ireland, typically dating from roughly the sixth to the twelfth century. A rath consists of a roughly circular area defined by one or more earthen banks, with a fosse, or external ditch, dug to provide the material for those banks and to reinforce the enclosure. At Carrowrevagh More, the bank forms a circle just under fifty metres in diameter. The fosse remains visible along the southern, northern, and north-eastern arc, suggesting it has been partially infilled or obscured elsewhere, possibly through centuries of cultivation or slippage on the slope. An entrance gap survives at the east-south-east, which would have been the original point of access into what was once, in all likelihood, a farmstead belonging to a family of some local standing. Raths were not fortifications in any military sense; they were status markers and practical enclosures, protecting livestock and household from the everyday hazards of early Irish rural life.
