Summary

Irregular shaped inland promontory enclosure with a total site footprint of approximately 6.8ha is positioned at the W shore of Furnace Lough. It projects SE into the lake and access across the neck from the NW is barred by a substantial wall, which is clearly visible on satellite imagery (SH). The remainder of the enclosure is defined by Furnace Lough. No obvious entrance feature recorded. No evidence for any internal features on the surface. Interior under pasture with forestry at the E edge. First map depiction in first edition Ordnance Survey mapping and again in the second edition Ordnance Survey maps, where the enclosing elements are shown as a large field boundary. So much so that it is possible that this is no more than an agricultural enclosure
