No bank, no mound, no upstanding stonework marks it out. The only clue to its existence is the way the grass grows differently in a rough circle, a subtle variation in colour and texture caused by the ring-ditch, the encircling trench that once defined the barrow's boundary, still influencing drainage and soil conditions beneath the surface after thousands of years.

The site sits in rough wet pasture about fifteen metres south-west of the River Mahore, which traces the townland boundary between Coolalough and Oldtown. It was recorded by C. Tarbett in 1987, who catalogued it as 'Site 4' in a survey that identified four barrows in the area. Tarbett noted that the remains could only be traced through differential growth patterning in the ring-ditch, with no enclosing bank visible. The ditch measured approximately 7.70 metres north to south and 9 metres east to west. A ring-ditch barrow, broadly speaking, is a burial monument of prehistoric origin defined by a circular trench, sometimes with an earthen bank and a central mound, the whole ensemble marking a place of interment or ritual significance. This particular example never made it onto the Ordnance Survey's historic maps, and aerial photography taken between 2005 and 2012 recorded no surface remains at all. More recently, satellite imagery on Google Earth has suggested the faint outline of a circular cropmark or possible pond feature at the location, which may represent the ghost of the ditch still showing through.

Access to the site is not straightforward, situated as it is in rough, likely waterlogged pasture on private farmland. The River Mahore runs close by, and the ground in this part of Limerick is the kind that discourages casual wandering, particularly in wetter months. Anyone with a serious interest in visiting would need landowner permission and appropriate footwear for boggy conditions. The monument offers nothing dramatic to the naked eye on a site visit; what makes it worth attention is precisely its near-total invisibility and the knowledge that something ancient persists here, readable only in the reluctant, uneven growth of grass over a ditch that has been silently filling for millennia.
