These platforms are among the quieter categories of Irish monument, easy to overlook in a landscape that tends to draw attention towards more obviously dramatic features, yet they represent the ordinary geography of early settlement, the practical business of finding or making a dry, stable place to live in a wet and often waterlogged country.

Settlement platforms of this kind are found across Ireland and are associated with a broad sweep of periods, from the early medieval centuries through to the post-medieval era. They are sometimes natural glacial features that were exploited for habitation, and sometimes wholly or partly artificial, built up with earth and stone to raise a dwelling above damp ground. In the west of Ireland, where bogland and poorly drained soils made low-lying ground difficult to occupy, even a modest elevation could make the difference between a habitable site and an unusable one. Culleenduff itself is a small rural townland in Sligo, a county whose landscape carries an unusually dense record of prehistoric and early historic activity, from megalithic tombs on the Carrowmore plain to the great passage tomb complex on Knocknarea.
