That is more or less what happened. Peat bogs are remarkable preservers of organic material, and timber that would rot to nothing in open air can survive for centuries, or millennia, locked in the cold, acidic, oxygen-poor environment of a working bog.

The three roundwoods, each with a diameter of roughly five centimetres and a collective width of about one and a quarter metres, were found during a 1995 pilot survey carried out by the Irish Archaeological Wetland Unit, based at University College Dublin. The survey was part of a broader investigation of the Littleton Works, a peatland area that takes its name from the nearby Littleton Bog, one of the better-studied raised bogs in the Irish midlands and south. Raised bogs are dome-shaped accumulations of sphagnum moss and decayed vegetation that have been building up since the end of the last ice age, and the Littleton Works sits within this kind of landscape. The modest dimensions of the three posts suggest a small structure, possibly a platform, a trackway element, or some other functional feature built to allow movement or activity across otherwise impassable wet ground. Without further excavation or dating evidence in the available record, the precise age and purpose of the structure remain open questions.
