The overall alignment follows a north-north-east to south-south-west axis, suggesting this was not a random scatter of timber but something deliberate, a structure intended to go somewhere, or to stop something, or to mark a boundary across wet ground.

The feature was found in 1995 by the Irish Archaeological Wetland Unit, based at University College Dublin, during a pilot survey of an area known as Littleton Works. Wetland archaeology of this kind depends heavily on the preserving qualities of peat, which, being waterlogged and low in oxygen, can hold organic material including wood for thousands of years in conditions that would destroy it almost anywhere else. Post rows and stake alignments recorded in Irish bogs have been interpreted variously as trackways, fish traps, enclosure boundaries, or structures associated with ritual activity near water, though without excavation and dating it is rarely possible to say with confidence which function applied in any given case. The Killeen site, with its narrow double and triple arrangement of stakes running across the bog, fits a pattern known from other wetland contexts across Ireland, but its precise date and purpose remain unestablished.
