What survives of a double moated platform site at Warrenstown amounts to little more than a faint stony rise, barely two to three centimetres above the surrounding drained land. That near-invisibility is itself part of the story: when the site was visited in 1987, both enclosures had been levelled relatively recently, the result of agricultural pressure rather than any deliberate act of clearance.

The site originally comprised two conjoined moated enclosures, a type of monument common in medieval Ireland and often associated with manorial settlement, in which a raised platform was surrounded by a ditch or moat as a combination of drainage, status display, and modest defence. Here the two platforms together covered more than 4,600 square metres in total, with a dry moat recorded at 2.60 metres wide and 1.50 metres deep. Dry stone walls of two buildings were still visible on the platform when the site was described by Barry, and the first edition Ordnance Survey six-inch map of 1839 shows three structures within the western enclosure, oriented in different directions across the site. These buildings are thought to be 18th or 19th century in date, though they likely occupy ground with a considerably older history beneath them. The river itself has shifted in that time: the River Goul, which flows roughly north to south, was diverted by a new channel dug sometime between 1839 and 1900, bringing it to within about ten metres of the monument, where it had previously run some hundred metres to the west. That quiet rerouting of water across agricultural land is its own small record of how thoroughly this landscape has been reorganised over two centuries of drainage and improvement, leaving the moated platforms as an almost erased footnote within it.
