Spread across roughly three hectares, a series of irregular fields defined by low earthen banks and fosses, the fosse being a ditch or cut that typically accompanied a raised bank and together formed a boundary, occupy the wedge of land between that road and the River Liffey to the south. The irregularity is part of what makes the system interesting. Planned, rectilinear field layouts are associated with later periods of agricultural reorganisation, particularly the improving landlordism of the eighteenth and nineteenth centuries. Irregular boundaries like these tend to speak of older, more organic arrangements, shaped by the particular needs and negotiations of communities working the land over long stretches of time.

The field system is not easily read from the ground, which is why its clearest documentation comes from aerial photography. Seen from above, the banks and fosses resolve into a coherent, if uneven, patchwork that ground-level observation might easily miss or mistake for natural undulation. The site sits in a part of Wicklow where the upper Liffey valley threads through upland terrain, and the three hectares preserved here represent a small but legible fragment of how that landscape was once divided, worked, and bounded. Beyond the aerial evidence and the approximate extent of the earthworks, the historical record for this particular site is thin, and any attempt to assign it a precise date or cultural context would be speculation.
