What is recorded here
Rathglass is a circular earthwork on a steep rise above the River Deel in County Mayo, marked on maps since 1838. Its stone-edged bank and hidden ditch still shape the grass, while thorns and brambles guard the place against easy entry. The view runs far along the river valley, suggesting the site was chosen to be seen, remembered and perhaps avoided.
In rough pasture, located on a prominent rise, from which there is a steep fall of ground to the River Deel which lies 55m to S and marks the townland boundary. The location overlooks a bend in the river, and there are excellent views to SE and SW along the river valley.
Named ‘Rathglass’ on the 1838 and 1922 OS 6-inch maps, this rath consists of a raised circular area (25.3m N–S; c. 25m E–W) defined by a bank of earth and stones, and enclosed by a fosse and an external bank, evident now only on the W half.
The inner bank (Wth 3.6m; int. H 0.8m; ext. H 1.4m, at N) is best preserved at NW–NE, but is reduced elsewhere to a scarp retaining only a slight internal rim; stones protruding along the inner edge may be remnants of a kerb. The fosse is evident at SE–W as a terrace (Wth 1.7m), with a fall of ground on its outer edge; at SE-S the terrace has an almost vertical scarp faced with stones, the result of being incorporated into a later field boundary. At W–NNE the fosse can be traced as a shallow depression (Wth 1.6-2m), and is defined on its outer edge by the external bank, which is reduced to a low, sod-covered rise (Wth 1.6-2m; ext. H 0.2m). The fosse and external bank cannot be traced on the E arc, where remnants of a linear N-S field fence (Wth 1.2m) overlie their line.
The NW quadrant appears to be at a slightly higher level than the rest of the interior, which is level. The entrance may have been at SE where there is a gap or break in the bank, now obscured by overgrowth.
The perimeter is ringed with thorn bushes, gorse and brambles; the interior is grassy with clumps of ferns and brambles. There is a structure (MA038-044001-) located 15m to N.

Rathglass, Mauteoge is a ringfort situated on a prominent rise overlooking the River Deel, typical of early-medieval defensive or agricultural settlements in Ireland. Local tradition associates such sites with fairy folklore, and this rath may have been considered a threshold between the human and supernatural worlds.
