That alone is worth pausing over.

The enclosure is a rath, the Irish term for a roughly circular or oval earthen enclosure typically associated with early medieval settlement and farming, though many examples were in use or venerated long after that period. This particular example measures approximately 45 metres north to south and 35 metres east to west, defined by an earthen bank some six to six and a half metres wide, which rises about two metres above the ground outside it while presenting a more modest internal face. Beyond the bank sits an external fosse, a drainage or defensive ditch roughly half a metre deep, with its base measuring around three and a half metres across. A small stream curves around the monument to the south-west, joining a larger watercourse to the north, and the whole thing sits on a gentle rise that would have given its original occupants a modest but useful view across low-lying ground. The entrance faces east-south-east, with a causeway crossing the fosse, though both appear to have been widened at some point. A counterscarp bank, a secondary earthen ridge on the outer edge of the fosse, runs across the entrance to the north-east and south, suggesting the approach was once more deliberately controlled than it looks today. The site was recorded as "the rath of Goblistown" in the Civil Survey of 1654 to 1656, marking it as a point on the boundary of Ambrosetown parish, which tells us it was visible, recognised, and considered significant even when the surveying was purely administrative.
