During routine cable-laying works, archaeological monitors found a short clay-bonded wall running north to south, preserved about half a metre high, sitting on peaty silts. Alongside it, three timber stakes were still holding their planks in place, as though the whole arrangement had simply been sealed into the ground and forgotten. The total length of the structure came to around ten metres, modest enough to suggest it was never intended as a permanent solution.

The find, recorded during monitoring in 2004 and reported by Stafford in 2007, is interpreted as a possible temporary sea-wall. The peaty silts on which it rests point to a foreshore or marginal wetland environment, consistent with what is known of Wexford's early waterfront. The town's quayside and street layout have shifted considerably over the centuries as land was reclaimed and the harbour edge pushed outward, and structures like this one offer a rare glimpse into the provisional, incremental nature of that process. A clay-bonded wall, reinforced with planks staked into soft ground, speaks less to grand civic engineering than to a practical, localised effort to keep water at a manageable distance, at least for a time.
