The site once held a tree-ring, a formally planted circle or ring of trees used as an ornamental feature in the grounds of a nineteenth-century house, and it has since been destroyed entirely. What remains is a recorded location, a kind of archaeological footnote to a vanished piece of designed landscape.

Tree-rings were a modest but deliberate form of estate ornamentation, used by landowners to give structure and visual interest to the grounds around their houses. Typically planted in a circular arrangement, sometimes around a central feature, they were part of the broader vocabulary of designed landscapes that became fashionable in Ireland during the eighteenth and nineteenth centuries. The Garrane example stood in front of a nineteenth-century house, presumably laid out as part of the same period of improvement that produced the house itself. What makes it slightly curious is that it does not appear on the first edition Ordnance Survey six-inch map, the large-scale mapping project carried out in Ireland during the 1830s and 1840s, which suggests the tree-ring may have been planted after that survey was completed, or was simply not considered significant enough to record at the time.
