What makes it quietly puzzling is the absence of any obvious entrance. The bank simply encircles a level, dry interior, opening to the east in a penannular form, that is, almost but not quite completing a full ring, like a letter C rotated, with no clear threshold to mark where anyone would have passed through.

The monument was surveyed by the Archaeological Survey of Ireland in 1999 and recorded in some detail. The raised interior measures approximately 20 metres east to west and 18 metres north to south. An earthen bank, around 4.1 metres wide, runs from the south around the west to the north-west, standing roughly half a metre above the external ground level. From the north-west around to the east and back to the south, this bank diminishes to a low scarp, just 10 centimetres high. An external fosse, a shallow ditch running outside the bank, measures nearly 6 metres across at its widest and roughly 30 centimetres deep. The 1897 edition of the Ordnance Survey 25-inch map already depicted the earthwork in its penannular form, and aerial imagery from 2005 through to 2018 continues to show it as an unplanted circular feature, partially outlined by trees. Two further enclosures lie within 160 metres to the north and north-west, suggesting this part of Moanroe townland, in the barony of Coonagh, was once a more populated or actively managed landscape than its present forestry cover implies.

The site lies 22 metres east of the townland boundary with Ballyvalode, within young commercial forestry that can make on-the-ground navigation less straightforward than aerial images suggest. The interior is noted as level and clear of overgrowth, which means that once found, the earthwork reads relatively well underfoot. Overhead imagery remains the most useful tool for orienting yourself before visiting, and the Google Earth record from November 2018 gives a good sense of the circular outline against the planted rows around it.
