At Creakan in County Wexford, a substantial prehistoric enclosure that once sat on a north-facing slope survived long enough to be recorded on Ordnance Survey maps in both 1839 and 1925, and then was quarried entirely out of existence. Nothing of it remains.

What the maps captured was a bivallate enclosure, meaning a roughly circular earthwork defined by two concentric banks and ditches rather than one. The inner diameter ran to approximately 40 metres, with the outer circuit reaching around 75 metres across. Enclosures of this type are associated broadly with later prehistoric and early medieval activity in Ireland, and their double-bank construction often signals a site of some importance or defensive intent. This one occupied a considered position on the landscape, on a slope looking north towards a col, a low pass between higher ground, situated roughly 400 metres to the northeast. Ballylane Hill rises about 1.2 kilometres to the southwest, and a lower ridge runs northeast to southwest about 500 metres to the north. The enclosure, in other words, looked out across a natural corridor through the hills. Whether it was a defended farmstead, a place of assembly, or something else entirely, the quarrying that removed it took those answers with it.
