Rough Fort is a counterscarp rath located near Limavady in County Londonderry, Northern Ireland. This early Christian earthwork comprises a roughly circular enclosure defined by an outer bank and ditch arrangement characteristic of the rath form. The monument sits upon bedrock of the Roe Valley Group, composed of Tournaisian-age sandstone and conglomerate with subordinate argillaceous rocks, geology that would have influenced both the construction and survival of its earthen defences.
The counterscarp configuration—where the outer bank faces outward from the ditch rather than inward—represents a distinctive variant within the broader tradition of Irish ringforts. Such monuments typically date to the early medieval period and functioned as defended homesteads for farming communities. The scale and form of Rough Fort suggest a settlement of modest status, its defences sufficient for domestic security rather than military defence.
The site is recorded and protected as a scheduled monument by the Historic Environment Division of the Department for Communities, Northern Ireland, under reference 11464. Rough Fort contributes to the archaeological record of early Christian settlement patterns in the Roe Valley, a region with substantial remains from this formative period of Irish history.
