First, probably after 1700, its circular earthen banks were planted with trees to create a fashionable tree-ring, the kind of ornamental feature that Georgian landowners liked to arrange across their parkland landscapes. Then, tucked into the north-western quadrant of that same ringfort, a small rectangular structure was built, its footprint measuring roughly six metres by five, and it too was eventually abandoned and forgotten.

A ringfort, to be clear, is an enclosed farmstead of the early medieval period, typically defined by one or more circular earthen or stone banks. They are among the most common archaeological monument types in Ireland, but their fate varied considerably in later centuries. Some were ploughed flat, others left as grass-covered lumps in fields, and a few, like this one near Benison Lodge, were absorbed into the aesthetic schemes of eighteenth-century estate design. The rectangular building now visible within the ringfort is thought to be a summer house associated with the lodge, a small retreat of the kind that appeared across Irish estates in the post-1700 period, placed at a comfortable distance from the main house and often given a picturesque or elevated setting. The low rise in the surrounding pasture-land would have suited that purpose well, offering an outlook across the managed demesne without requiring a great deal of construction. The building's date remains uncertain, and the interpretation, while plausible, is not confirmed.

What remains today are the outline walls of the rectangular structure, visible within the tree-ring on the rise roughly 500 metres to the north-east of Benison Lodge itself. The site sits in pasture-land, and the layering of periods here, early medieval earthwork, Georgian ornamental planting, and the unidentified small building within, makes it an unusually compact example of how Irish estates sometimes made deliberate use of older monuments rather than simply working around them.
