This earthwork appeared on both the 1836 and 1908 Ordnance Survey maps, marking its presence in the landscape for well over a century before its removal around 1964. Local memory recalls the site as having particularly deep ditches, suggesting it was once a substantial defensive or agricultural feature in the rural Meath countryside.

Archaeological surveys conducted in 1968, just a few years after the enclosure’s destruction, revealed lingering traces of its former boundaries. The rectangular area measured approximately 63 metres from northeast to southwest and 56 metres from northwest to southeast, with its outline still visible through variations in grass growth patterns. The northwest and southwest sides were defined by existing field banks, whilst the northeast and southeast boundaries showed distinctive bands of vegetation; lighter grass marked where the banks once stood, measuring about 5.1 metres wide, whilst lusher growth on the outer edges indicated the position of the former fosses, or defensive ditches, at roughly 2 metres wide.

These subtle ground markings represent all that remains of Lisnaclogh today, a ghost impression in the landscape where centuries of agricultural activity once took place. The site forms part of County Meath’s rich archaeological heritage, documented in the Archaeological Inventory of County Meath and subsequently updated through ongoing research by local historians and archaeologists.
