By the time anyone thought to record it properly, the damage was already done.

The antiquarian Thomas Johnson Westropp documented the site in 1915, by which point it had already been quarried through its centre. His notes describe what had originally been a fairly substantial earthen platform, roughly 17 metres in diameter, ringed by a fosse, which is a defensive ditch, approximately three to four metres wide. Beyond that sat a low bank about two metres across, and then a second outer fosse of similar width, surviving to a depth of around one metre. The concentric arrangement, platform, ditch, bank, ditch, is characteristic of a class of earthwork found across Ireland, though their precise functions varied considerably, from ceremonial enclosures to early settlement sites. What this particular example was built for, and by whom, is not recorded in what survives of the historical and archaeological notes.

The demesne at Malahide, north of Dublin, is today largely accessible as a public park, and the grounds retain a number of mature trees and landscape features from its long period as a private estate. Anyone curious about the earthwork should be aware that its condition, even at the time of Westropp's early twentieth-century visit, was already compromised by the gravel quarrying at its core. What remains is likely a partial shadow of the original structure. The site was compiled for the archaeological record by Geraldine Stout and uploaded in August 2011, which at least ensures it exists in the formal inventory of Irish monuments even if the physical evidence on the ground is fragmentary.
