The bush is a sceach, a whitethorn or hawthorn, and in Irish folk belief these trees carried considerable weight when they grew near holy wells. They served as focal points for offerings and prayers, their branches sometimes tied with rags or small tokens by those who came seeking cures or intercession. The well this one marked, or stood close to, is long gone, and the housing estates of Kill of the Grange have grown up around the green that now contains it.

The well was recorded in sources dating back to at least 1895, when it appeared in Stokes's survey, and again in Daly's 1957 account of the area. Both references place it within the townland of Kill of the Grange, a name that itself carries early ecclesiastical associations, kill being derived from the Irish cill, meaning a church or monastic cell. The well was evidently still a physical presence well into the twentieth century, but at some point it was piped underground and then removed entirely in the early 1980s, according to local knowledge gathered by Liam Clare of the Foxrock Local History Club. That kind of quiet municipal erasure, pipes and culverts doing what simple neglect had not, is a familiar story for Irish holy wells caught between post-war suburban development and the slow erosion of the customs that once gave them meaning.

The sceach remains in the green space to the west of Hillview Drive, overlooking the small stream. It is an unassuming spot, the sort of place that registers as ordinary green infrastructure unless you are looking with some purpose. There are no markers or signage pointing to its significance. The best approach is on foot from Hillview Drive itself, following the edge of the green towards the stream. The bush is most easily identified in late spring, when hawthorn is in flower, though visiting out of season simply requires a closer look at what grows nearest the water's edge.
