Sometime after 1973, the embanked enclosure that had occupied a low north-to-south spur of land in County Wexford was removed, levelled out of the landscape by agriculture or development. What had survived long enough to be mapped twice, first on the Ordnance Survey six-inch edition of 1839 and again on the 1924 edition, was gone within decades of the second recording. The irony is that its erasure made it, in one sense, more legible. Ploughed or cleared ground over buried archaeology tends to produce cropmarks, the subtle variations in crop colour and growth that betray ditches and banks beneath the soil, and it is through aerial photography that the enclosure at Assagart now speaks most clearly.

The aerial photographs reveal a double-ditched enclosure, meaning two concentric rings of cut features surrounding the interior, with a maximum external diameter of around sixty metres. Inside, a circular hut-site of roughly ten metres in diameter is visible, suggesting domestic occupation at some point in the site's past. Attached to the north-east is an annexe, a secondary enclosure defined by a single fosse, which is essentially a ditch or trench, measuring approximately thirty metres east to west and twenty metres north to south. This kind of enclosed settlement, a main circular enclosure with an attached subsidiary space, is a layout known from Iron Age and early medieval contexts across Ireland, though the notes here do not fix Assagart to a specific period. The cropmark evidence was confirmed again in digital aerial photographs taken in 2006, more than three decades after the physical remains had been cleared away.

The site sits on the spine of a low spur, a position that would have offered modest elevation and visibility over the surrounding ground, a typical preference for enclosed settlements of this type. For anyone visiting the area today, there is no earthwork to trace or bank to walk along. The enclosure exists now only in archive photographs and in the soil itself, waiting, in the way that buried things do, for the right conditions to show through.
