No trace of it appears on aerial photography, and it left no mark on the Ordnance Survey's historic mapping. The sole cartographic record of it comes from Larkin's 1808 map of County Westmeath, a single source that confirms the monument was already known by that date, even if no one thought to record what exactly it was meant to be.

By the time anyone looked closely at the site, in 1984, it had been reduced to a semi-circular earthwork roughly fifteen metres across from north to south, defined by a low bank between two and three metres wide enclosing a level interior area. There was no obvious fosse, the term for a defensive ditch that typically accompanies earthworks of this kind, which makes its original purpose harder to pin down. The story becomes more layered when you consider the surrounding landscape. The 1837 edition of the Ordnance Survey six-inch map shows a road running east to west through or near the site, a road that no longer exists as a physical feature but whose ghost survives as a cropmark, a faint discolouration visible in the soil of the field to the east, where the buried remains of the old surface affect how grass or crops grow above it. A modern field fence running roughly north-east to south-west now bisects the monument, or at least skirts its eastern edge, adding one more layer of disruption to a site that has been quietly disappearing for a very long time.
