It is not a castle or a fortification but a belvedere, a purpose-built ornamental structure designed to give its occupants an elevated view across the surrounding countryside. Such follies were a familiar feature of eighteenth-century demesne design in Ireland, where landowners shaped their estates not just for agriculture but for aesthetic effect, placing towers, temples, and ruined arches at calculated points in the landscape to frame a view or punctuate a walk.

The structure is roughly square in plan, measuring just under 5.6 metres internally in both directions, and is built from random-rubble stone with some brick used in alterations or repairs. The south elevation survives to its full height, with a central window on each floor, while the north wall retains two small ground-floor openings and a larger window above. A possible door opening faces east, though the first-floor window on that side has been blocked with brick. By 1842, when it appeared on the Ordnance Survey six-inch map, it was simply labelled "Turret". The historian Charles Smith, writing in 1750, was rather more expressive, describing it as "a turret with a luxurious prospect of a great tract of country", which suggests the tower was already well established as a viewing point by the mid-eighteenth century and that the view it commanded was considered worth remarking upon.
