The boundaries themselves are the site, marking out the limits of a community's working ground on a slope that tilts from gentle to steep before dropping away into a narrow, steep-sided valley below.

Field systems of this kind are among the less celebrated categories of archaeological site in Ireland, easily overlooked in favour of more visible monuments, yet often just as telling. Where a ringfort or a church announces itself, a field system speaks in a lower register, through the logic of enclosure and land division. At Kilbaylet, the arrangement of these old boundaries indicates a settlement site, meaning the fields were not isolated agricultural features but part of a broader pattern of habitation. The detail was recorded by J. Brindley, and included in the Archaeological Inventory of County Wicklow published in 1997. Beyond that, the record is spare, which itself says something about how sites like this tend to fare, noted, catalogued, and then left to the slope and the weather.
