What was once a defined enclosure, roughly 33 metres in diameter, has been gradually absorbed into the surrounding farmscape; a field bank now overlies part of its boundary, leaving only a scarp, a low step in the ground, to trace the western, northern, and eastern arc of the original structure.

A rath is a ringfort, a form of enclosed farmstead typical of early medieval Ireland, generally dating from somewhere between the sixth and tenth centuries, though many were reused or adapted long after their initial construction. They were built by farming families as a combination of dwelling and livestock enclosure, and they appear in their thousands across the Irish landscape, from elaborate multivallate examples to modest earthworks like this one. The Woodfield rath falls into the latter category, its single enclosing element now largely indistinct. What makes its setting slightly more arresting is the presence of a miscellaneous burial recorded approximately 30 metres to the north-west. Such burials, found near ringforts across Ireland, are sometimes associated with early Christian or pre-Christian practice, though their precise relationship to the enclosures they neighbour is rarely straightforward to interpret. The site was noted by Knight around 1975 and later included in the Archaeological Inventory of County Galway, compiled by Olive Alcock, Kathy de hÓra, and Paul Gosling, published in 1999.
