On a prominent east-west ridge in County Clare, with a marshy estuary stretching away to the north, this earthen enclosure commands clear views in every direction, and a near-identical companion fort sits just to its east, the two of them occupying the high ground together in a pairing that raises quiet questions about how and why they came to be neighbours.

A rath, to give it its Irish term, is an early medieval farmstead enclosed by one or more earthen banks and ditches, typically dating from somewhere between the sixth and tenth centuries. This example at Dough is subcircular in plan, its interior measuring roughly 28 metres across in both directions, though the overall structure, including its banks and outer earthwork, extends to nearly 59 metres north to south and just over 53 metres east to west. The enclosure is defined by an inner bank, a steep-sided, flat-bottomed fosse or ditch running two to three metres wide, and a second outer bank beyond that. The entrance is on the eastern side, reached by a causeway, a raised strip of ground left uncut across the fosse to allow passage, running about four to five metres wide and sitting roughly 0.6 metres above the base of the ditch. The interior slopes gently northward. The external bank has suffered some disturbance from cattle at the south-southwest, and gaps have been made through both banks at various points, though the perimeter itself remains densely overgrown. A preservation order has been in place since 1987, recognising the monument's legal protection under the National Monuments Acts.

The second rath, visible from the eastern entrance of this one, sits approximately 45 metres away across the same ridge. Whether the two enclosures were in use simultaneously or represent different phases of occupation on a particularly favourable piece of ground is not recorded, but the ridge position, with its long views over the estuary and surrounding pasture, makes it easy to understand why someone kept coming back to build here.
