The rath at Reens West does the opposite. It sits in low-lying marshy pasture at the base of a north-east-facing slope, hemmed in by streams on two sides, its external ditch still waterlogged. Whatever logic governed its positioning here, it was not the logic of visibility or easy drainage.

A ringfort, or rath, is a roughly circular enclosure built during the early medieval period, typically between the fifth and twelfth centuries, and used as a farmstead and place of security for a family and their livestock. This example is oval rather than perfectly circular, measuring approximately 35 metres on its north-west to south-east axis and around 30 metres across. It is enclosed by an earth-and-stone bank that rises to about 0.7 metres on the interior face and 1.2 metres on the exterior, with a waterlogged fosse, or ditch, running around the outside. That fosse is roughly 2.6 metres wide and 0.35 metres deep, and it remains wet enough today to qualify as waterlogged. A gap of about 1.6 metres in the bank on the south-east side marks what was likely the original entrance. Old field drains open into the fosse at the east-south-east and west, and a more recent drain to the north-east connects the fosse with one of the nearby streams, suggesting the site has been managed and modified by successive generations of farmers long after its original occupants were gone. The record was compiled by Denis Power and uploaded in August 2011.

Accessing the site is not straightforward. The bank and the interior are densely overgrown with bushes, and only a narrow band around the inner edge can actually be reached on foot. The surrounding pasture is marshy, and the waterlogged fosse reinforces the point that this is wet ground in all but the driest months. What a careful visitor can observe is the profile of the bank itself, the slight depression of the fosse, and the south-east entrance gap, which remains the clearest surviving architectural detail. The streams bordering the field to the north-east and north-west give some sense of why the site feels enclosed even from the outside, tucked into its corner of the landscape rather than rising above it.
