The ground is steep, thick with furze, and drops away into a valley that no longer holds water. Whatever drew people here, it was not convenience, and that tension between effort and location is what makes this site quietly arresting.

The monument at Ballinascorney Upper is a ring-barrow, a type of prehistoric funerary monument in which a burial mound is encircled by a bank and ditch, marking out a boundary between the world of the living and whatever the builders understood the dead to occupy. What distinguishes this particular example is its construction: Healy, writing in 1975, identified it as double-banked, meaning it carries two concentric banks rather than the more common single enclosure. That additional circuit of earthwork represents a significant extra investment of labour, though the reasons behind such a choice, whether ritual, social, or purely practical, remain unclear. Further along the slope, to the south-west of the barrow itself, there are man-made terraces cut into the hillside. These are a separate feature, and their relationship to the barrow, whether contemporary, earlier, or later, has not been firmly established. Compiled by Geraldine Stout and Padraig Clancy, the site record was last revised in July 2018.

Ballinascorney Upper lies in the foothills of the Dublin Mountains, accessible via the minor roads that run south from Tallaght and Bohernabreena. The terrain is open but rough underfoot, and the furze that covers the slope can make progress slow and scratchy outside of winter months when the vegetation is lower. The dried-up valley below the barrow is worth pausing over: its absence of water is now a defining feature of the landscape, though it would once have looked quite different. The double banking is best appreciated by walking around the monument rather than simply approaching it from one direction, since the earthworks are subtle and the steep gradient can compress your sense of scale.
