Counterscarp platform rath is a early medieval ringfort situated near Lisburn in County Antrim, Northern Ireland. The monument consists of a single substantial bank with an external ditch or counterscarp platform, a defensive arrangement typical of Irish raths from the fifth to tenth centuries. The site occupies bedrock composed of Palaeogene extrusive rocks, principally mafic lavas and tuffs laid down during the Paleogene period, which would have presented a firm foundation for the substantial earthwork.
The rath's form suggests it served as a defended dwelling or livestock enclosure for a family of considerable status within early medieval Irish society. The counterscarp platform—the flat space created between the inner ditch and outer bank—represents a deliberate enhancement to the fort's defensive capability, allowing additional space for movement or additional defensive positions. Such refinements are characteristic of more elaborate ringfort designs.
The monument is protected by the Historic Environment Division under reference 4523 as a scheduled historic monument. Its survival in the landscape near Lisburn preserves evidence of settlement patterns and defensive strategies employed during the early Christian period in Ulster, when such fortified enclosures formed the dominant form of aristocratic rural settlement across Ireland.
