A coastal promontory fort is among the more elemental forms of early Irish fortification: the sea does most of the work, cutting off three sides of a headland, and whoever built the fort needed only to construct a bank, ditch, or wall across the narrow neck of land connecting it to the mainland. The result is a naturally enclosed space that could serve as a refuge, a settlement, or a statement of territorial control.

Such forts are found at intervals around the Irish coast and are generally associated with the Iron Age, though some were in use across a broader span of prehistory and early medieval times. The land here falls within an area recorded as Corporation Lands in County Wicklow, suggesting a stretch of coastal ground that has passed through various forms of communal or civic ownership over the centuries. Beyond the fort's location and its classification as a coastal promontory type, detailed information about its construction, dimensions, or excavation history is not currently available in the public record.
