The ringfort recorded at Mauricetown in County Limerick falls firmly into the second category. What was once a rath, a type of circular earthen enclosure typically dating to early medieval Ireland and used as a farmstead or defended residence, now leaves no visible trace on the ground. The marshy pasture that covers the site gives nothing away.

The monument was documented on the Ordnance Survey six-inch map of 1841, where it appeared as an embanked circular enclosure with a diameter of approximately thirty metres, sitting on a break in a northeast-facing slope. That survey, produced with considerable care across the whole island during the 1830s and 1840s, captured many earthworks that subsequent generations of farming, drainage, and land improvement would go on to erase. By the time Denis Power inspected the Mauricetown site in July 2010, the levelling was complete. His notes record no trace of the monument, though a separate notes field was flagged for further reference, suggesting the picture may not be entirely closed. The compiled record was uploaded to the database in August 2011.

For anyone making their way to Mauricetown, the marshy character of the ground is worth bearing in mind, particularly after wet weather, when the northeast-facing slope can be soft underfoot. There is nothing to see in the conventional sense, and that is rather the point. The value here is cartographic and archival as much as physical; arriving with a copy of the 1841 OS six-inch sheet, which is freely accessible through the map archives online, allows you to orient yourself to where the enclosure bank once ran and to think about what the landscape looked like when that circuit of earth still stood. The absence itself becomes something to read.
