The ring barrow at Brickfield in County Limerick occupies the poorly drained floodplains of the Graigue River, which runs directly past the site to the south. The 1840 edition of the Ordnance Survey six-inch map annotated this very ground with the note 'Liable to Floods', making the deliberate siting of a ceremonial monument here one of those quiet puzzles that Irish archaeology occasionally throws up.

A ring barrow is a low, roughly circular earthwork, typically of Bronze Age origin, consisting of a central raised area enclosed by a ditch and an outer bank. The example at Brickfield is reasonably substantial. Its internal diameter measures approximately 20 metres, while the full external diameter, taking in the surrounding earthworks, reaches around 50 metres. The monument's outline is defined by a scarp, an inner ditch, a bank, a second ditch, and an outer bank, giving it a multi-element profile that is more complex than the simplest examples of the type. Despite its location on ground that floods regularly, the monument has survived well enough to be clearly legible from aerial imagery, appearing on the 2005 OSi orthophoto, on Digital Globe imagery taken between 2011 and 2013, and on Google Earth imagery captured in March 2016. The record was compiled by Caimin O'Brien and uploaded to the national database in May 2020.

The site sits on private farmland beside the Graigue River, and the floodplain setting means that ground conditions can be poor, particularly in the wetter months. The monument is most legible from aerial or satellite imagery rather than at ground level, where the low earthworks can be difficult to read against the surrounding terrain. Visitors with an interest in the site would do better to examine the publicly available orthophotos online before making any attempt to locate it on foot, and to seek landowner permission before approaching. The spring and summer months, when water levels are lower and vegetation has not yet fully obscured the earthwork contours, offer the best chance of making out the circular form on the ground.
