The moat at Williamstown in County Meath once stood on the lower reaches of a west-facing slope, about 150 metres east of a small stream running from south to north.

When archaeologists documented the site in 1968, they found a raised, circular mound covered in grass and trees. The top of the mound measured 17 metres north to south and 15 metres east to west, whilst its base stretched considerably wider at 32 metres north to south. The structure rose between 1.7 metres on its northern side and 2.3 metres to the south, with steep scarps defining its edges.
What made this earthwork particularly interesting was the faint trace of a fosse, or defensive ditch, that could still be seen along its northern edge. This ditch, about 6 metres wide at the top and roughly 0.2 metres deep on the exterior, would have provided additional protection for whatever structure once stood atop the mound. By the time of the 1968 survey, quarrying had already damaged parts of the site; a relatively recent quarry pit had been cut into the northern scarp, whilst an older, grass-covered rectangular quarry marked the southern edge. No clear entrance to the enclosure could be identified.
Unfortunately, this remnant of medieval Ireland’s defensive landscape didn’t survive much longer. By 1986, the entire earthwork had been removed, leaving only the archaeological records to tell its story. The site was first recorded in the Archaeological Inventory of County Meath in 1987, with updates added as recently as 2022 to reflect ongoing research into these once-common features of the Irish countryside.
