This one at Stagmount offers none of that. Standing in the pasture on its south-westerly facing slope, you would see only grass and perhaps a field boundary. The ringfort here is entirely invisible at ground level, its outline legible only from the air.

A rath is an early medieval farmstead enclosure, typically defined by one or more circular earthen banks and ditches, and thousands of them survive across Ireland in varying states of preservation. The Stagmount example survives in a more ghostly form. An aerial photograph taken in 1977 revealed differential vegetation colour, meaning the grass and other plants within the buried circuit were growing or colouring differently from the surrounding pasture, tracing out a circular enclosure approximately 45 metres in diameter. This kind of cropmark or soilmark appears because buried features alter how moisture and nutrients move through the soil, which in turn affects how plants above them behave. Local knowledge had already hinted at something unusual, with people noting irregular growth patterns in the vegetation on either side of a more recent field boundary. A second possible rath has been identified roughly 50 metres to the south-west, which would make this a paired or clustered settlement of the sort not uncommon in areas of early agricultural activity.
