There is no earthwork to speak of, no upstanding bank or obvious depression. The only reliable way to see it is from above, where it appears as a positive cropmark, the buried ditch beneath causing crops to grow taller or greener along its course, tracing the outline of a near-perfect circle against the surrounding field. Cropmarks of this kind are fleeting things, appearing only under the right combination of crop type, soil moisture, and sunlight angle, which makes the Google Earth capture from June 2018 something of a fortunate record.

The enclosure sits roughly 40 metres south-east of the Ward River and about 230 metres west-south-west of Coolarath Bridge, close to the northern boundary of the field. Its defining feature is a ditch approximately 2 metres wide, enclosing a roughly circular area measuring around 56 metres east to west and 55 metres north to south. Circular enclosures of this general type are found widely across Ireland and can date from the prehistoric period through to the early medieval, though without excavation it is impossible to assign a date to this particular example. What complicates the interior picture is an irregular feature occupying the centre and western half of the site, which appears to correspond to a gravel pit marked on the Ordnance Survey First Edition six-inch map of around 1840. By the time the 25-inch OS map was produced around 1910, the same area is shown with tree symbols, suggesting the pit had by then been softened or screened by planting. The later activity has almost certainly disturbed whatever archaeology once lay at the centre of the enclosure.

The site is on private agricultural land and is not publicly accessible in any formal sense. For those with an interest in cropmark archaeology, the Google Earth imagery from June 2018 remains the clearest way to study the enclosure's shape and extent. The positive cropmark is most legible in that coverage when viewed at a moderate zoom level, where the circular ditch resolves clearly against the field. The area around Coolarath Bridge provides a rough geographical anchor for locating the field, which lies along the western side of the Ward River corridor in north County Dublin.
