This structure is shown on the 1:2500 Ordnance Survey map of 1899 and appears to be roofed although the map is a little unclear and it could just be showing the three cells that the structure is shown is divided into on the 1918 map. Overall it measured 13 metres northwest to southeast by 4 metres. Now it is ruinous and overgrown with bracken. It had a small enclosure around it to the north and east. J.J.
