The earthwork that once rose here, large enough to be mapped in 1839 with an external diameter of roughly fifty metres, has long since flattened into the surrounding field. It was already a "low mound" by the late nineteenth century, when the geologist and antiquarian G. H. Kinahan recorded it under the local name Garry Hasten 'moat'. To the naked eye today, the site has effectively disappeared.

What survives is visible only from the air. A series of aerial photographs taken in 2000 revealed a circular cropmark, somewhere between thirty and forty metres in diameter, formed by a fosse, that is, a ditch dug around a defended enclosure. Attached to its northern side is a second, subcircular enclosure of roughly fifty metres across, also defined by a fosse line. Together, the two features suggest a rath with an annexe, a type of enclosed farmstead common in early medieval Ireland, where a ringfort-style enclosure was supplemented by an additional attached compound, possibly for livestock or dependants. Cropmarks of this kind appear when buried ditches affect how grass or crops grow above them, leaving outlines that only become legible from height or in dry conditions when soil moisture differences are most pronounced. The Derry River runs about thirty metres to the west, and a smaller east-west stream joins it roughly seventy metres to the south, placing the site neatly in the floor of a sheltered north-south valley. An abbey site lies approximately fifty metres to the east, suggesting this corner of County Wexford was a place of some significance over a long stretch of time, even if the ground itself now gives little away.
