Measuring approximately 66 metres north to south and 105 metres east to west, the feature is substantial enough to suggest it was once a significant modification of the landscape, yet it attracts almost none of the attention given to the more celebrated earthworks of the Irish midlands.

What makes it particularly difficult to read is a field boundary, constructed sometime after 1700, that cuts straight through the middle of it, slicing the earthwork in two as though it were simply another inconvenience to be divided and managed. Aerial photography has been the main tool for piecing the feature back together visually. The working interpretation is that it may be the remains of a raised field, the kind of elevated or embanked cultivation plot associated with organised land drainage schemes. Supporting this reading is the evidence of field drains extending away from the north-east and south-east corners of the earthwork, suggesting that at some point water management, rather than fortification or ceremony, was the primary concern here. Raised fields of this kind were a practical response to the boggy, waterlogged conditions that characterised much of the Irish midlands before large-scale drainage works altered the hydrology of the region over the eighteenth and nineteenth centuries.
