This one exists primarily as a shadow in a field, visible only from the air. On a gently north-facing slope at Connagh in County Wexford, a ringfort survives not as a raised bank or a hollow you might stumble into, but as a cropmark, a pattern in the vegetation that emerges in aerial photographs when the soil beneath betrays the outline of something long buried or flattened. Three concentric fosse features, the word fosse referring to the ditches that would originally have enclosed and defended the settlement, trace a circular form with an interior diameter of roughly 25 metres and an overall external diameter of around 45 metres. The marks are described as very faint, which says something about both the site's condition and the patience required to read a landscape.

Ringforts, sometimes called raths when they were constructed primarily from earthen banks and ditches rather than stone, were the most common form of rural settlement in early medieval Ireland, built roughly between the fifth and twelfth centuries. They typically enclosed a farmstead and its inhabitants, providing a modest degree of security and a clear boundary between domestic and agricultural space. Thousands survive across the country in various states of preservation, but a significant number have been levelled by centuries of ploughing, leaving only these faint subsurface traces. At Connagh, the triple-fosse arrangement is of some interest, as most raths had a single enclosing ditch; additional ditches sometimes indicated higher-status occupation, though here the features are so faint that drawing confident conclusions is difficult. The site was recorded and described in the Archaeological Inventory of County Wexford, published in 1996.
