This monument is described by Stout (1991, 263) as:
This monument was discovered through aerial survey undertaken by Swan. It encloses the top of ‘Windmill Hill’, which rises slightly over the 120m contour. The enclosure lies on limestone and shale drift, upon which a grey-brown podzolic soil has formed, 1 km N of the River Hurley, a tributary of the River Nanny. Another enclosure (Kilbrew ME033-010----) is situated on the crest of a low ridge on the slope of Windmill Hill, 110m to the south-west. The Irishtown enclosure is in an extremely denuded condition. The bank has suffered from spade cultivation, which took place on the flanks of the hill in the preceding centuries. It is nonetheless possible to trace a continuous circuit of bank with a maximum overall diameter of 245m. The bank is best preserved to the N and W, where it varies in width from 10m to 22m, with a maximum height of 0.5m. There is no ditch, but there is a broad, shallow, scarped area inside the bank, 20-28m wide. In the east (87 degrees T) is a 22m wide break in the bank. Another possible entrance feature in the south-west (220 degrees T) has been partly obliterated by the site of a lime-kiln and quarry. The south-west arc of the bank runs up to the area of disturbance, but there is 27m gap south of the quarry.
