What is recorded here
Lismore is a circular earthen fort perched on a steep Mayo ridge, dropping suddenly into Newport Bay on both sides. Its bank still holds buried oyster and limpet shells, suggesting people lived there long before maps named it. The fort faces two inlets at once, as if set to watch every boat entering either water.
In pasture, located on top of a steep ENE−WSW ridge, on a peninsula jutting into the N side of Newport Bay. There is a steep fall of ground, reflecting the natural slope of the ridge, immediately to N and S of the rath. The rath overlooks a shallow sea inlet on the N side of the ridge, and over a larger inlet on the S side.
This rath is named ‘Lismore’ on the 1838 and 1920 OS 6-inch maps. It consists of a raised circular area (26m N−S; 25.5m E−W) defined by a bank (Wth 2.25m; H 0.85m at W), reduced to a scarp (H 2.5m) with a low internal lip at N and S. Stones protrude from the bank and from the S face of the scarp, and oyster and limpet shells are incorporated into the bank in parts. Traces of an external fosse were evident on the W half of the rath during an inspection in the first half of the 20th-century, but were not noted during a 1987 inspection. There is a break in the bank at WSW, but it is unclear if this represents an original entrance. A chapel (MA067-020003-) is indicated in the S half of the interior as 'Chapel (Site of)' on the 1920 OS 6-inch map, but no trace survives at ground level.
