Locally it is simply called The Grove. No entrance is apparent, no path leads in, and the bank, modest as it is, describes a complete suboval circuit that has more in common with designed landscape ornament than with any agricultural purpose. The oddity deepens when you learn that what looks like a decorative planting may well be something far older, quietly absorbed into the aesthetic ambitions of a nineteenth-century country house.

When the first edition Ordnance Survey six-inch map was compiled around 1840, the feature was recorded not as an antiquity but as a roughly circular grove of trees, suggesting that by then its original character had already been obscured or deliberately recast. By the time the twenty-five-inch revision appeared in 1897, it was mapped as a tree-planted enclosure. Archaeological Survey of Ireland fieldwork carried out in 2000 recorded a suboval earthwork measuring approximately 39 metres east to west and 28 metres north to south, with an earthen bank roughly 3.8 metres wide and a shallow external fosse, a ditch running around the outside of the bank. A ringfort, the term for an early medieval enclosed farmstead typically defined by one or more earthen or stone banks, sits just 95 metres to the south, and surveyors Alison McQueen and Vera Rahilly noted that this monument may itself have originated as a ringfort before being modified as a demesne feature associated with Jockey Hall, a house situated approximately 280 metres to the south-east and dated to between 1810 and 1830. The practice of incorporating or reshaping pre-existing earthworks into designed landscapes was not uncommon among improving landlords of that period, who sometimes valued the visual effect of a wooded mound without troubling much about what lay beneath it.

The site sits in working pasture and there is no formal public access, but the ring of beeches is visible from the surrounding area and the earthwork shows clearly on aerial imagery. The bank is incorporated into a field boundary along its western arc, which is worth bearing in mind when trying to read the shape on the ground. Winter or early spring, before the beech canopy fully closes, offers the clearest view of the bank and its relationship to the surrounding field. A second ringfort close by to the south makes the immediate landscape around Jockeyhall unusually layered, with early medieval enclosure, post-medieval improvement, and Victorian mapping all contributing to what now appears, at a glance, to be nothing more than a pleasant stand of old trees.
