The transformation is so thorough that only the circular geometry of the garden gives the game away. A ringfort, or rath, is an enclosed farmstead typically dating from the early medieval period, defined by one or more earthen banks and ditches. This one, in Wolfesburgess West, has not been erased so much as absorbed.

The 1841 Ordnance Survey six-inch map shows the monument as an isolated embanked enclosure, roughly twenty metres in diameter, sitting alone in the landscape. At some point after that survey, the ringfort was drawn into the grounds of Fort George country house and remade as a garden feature. The earthen bank, which runs from south-southwest to north-northeast and still survives to an external height of about half a metre, has been paved over with stone and brick. A footpath now follows its line. The interior, measuring approximately 21.5 metres north to south and 24 metres east to west, lies under lawn, with a small paved circle of around four metres in diameter at its centre, occupied by a sundial. Steps connect the interior to the adjoining house from the south-southwest and southeast. The record was compiled by Denis Power and uploaded to the national monuments database in August 2011.

Access to this site depends entirely on access to the Fort George property, as the ringfort now forms part of a private garden rather than open ground. The circular bank is the thing to look for, low and easily missed if you are not expecting it, its original profile softened by the paving laid over it. The sundial at the centre marks what was once the domestic space of an early medieval household, the kind of enclosed farmstead that once dotted the Irish countryside in its thousands. That domestic continuity, an ancient enclosure still in daily use as a garden, is the quietly peculiar detail that makes this one worth noting.
