There is nothing to see at Greenan Mote, and that, in its way, is the point. The low, flat earthwork that once rose from the flood-plain of the River Suir in County Waterford was demolished around 1960, leaving no visible trace at ground level. It survives now only in maps, a brief scholarly note, and the category of things that were destroyed before anyone thought too hard about what they might have been.

A mote, in the Irish medieval context, is an earthen mound, typically associated with the Norman motte-and-bailey form of fortification, where a raised earthen platform supported a timber tower and was accompanied by an enclosed courtyard. The Ordnance Survey's six-inch map of 1840 records this particular example faintly, as an oval feature measuring roughly 60 metres north to south and 30 metres east to west, sitting on the western side of a low hill in the Suir flood-plain. By the 1922 edition of the same map it is described as a scarped hillock, the sloped edges suggesting deliberate shaping rather than natural accumulation. Both editions name it Greenan Mote. P. Lyons, writing in the Journal of the Royal Society of Antiquaries of Ireland in 1934, described it as a low, flat, and circular mote in a piece cataloguing earthworks near Clonmel, apparently noting it without any particular alarm about its condition. Within a generation it was gone, removed sometime around 1960, its material presumably cleared for agriculture or development in the river plain below Clonmel.
