Rathclogh

Rathclogh is an archaeological place in County Tipperary, Ireland. It holds a low circular earthwork, barely thirty centimetres high, that surveyors first mapped as a neat twenty-metre enclosure in 1840. Later maps read the same slight mound as an oval twenty-five metres north to south and twenty metres east to west. The source says that shift likely reflected changes in ground vegetation and visibility rather than a structural alteration.
