The posts extend across a length of just 2.5 metres, which makes the structure modest in scale but quietly perplexing in purpose. Some are hazel, others alder, all in a poor state of preservation, and several horizontal rods were found lying at right angles across them. What exactly the thing was built to do remains an open question. The best current suggestion is that it served as some kind of platform or jetty, a landing point at the water's edge, though nothing about its surviving form confirms that conclusively.

The structure came to light in 1992 during a systematic survey of archaeological monuments in and around Lough More, carried out by the Irish Archaeological Wetland Unit. Wetland archaeology of this kind tends to preserve organic materials that would long since have vanished on dry land; waterlogged conditions slow the decay of wood, which is why posts driven into a lakebed centuries ago can still be identified by species. Hazel and alder were both common choices for wetland construction in early Irish contexts, hazel for its workable rods and alder for its particular resistance to prolonged exposure to water. The horizontal rods noted alongside the uprights hint at a woven or reinforced structure, though whether this represents an integral part of the original design or material that accumulated there later is not recorded.
