@)National Geographic Society Finlay Photograph by Bernard F.Rogers, Jr. SUCH ROUND TOWERS ARE COMMON IN IRELAND, BUT NO ONE KNOWS WHYTHEY WERE BUILT Druids may have erected them for fire temples, but more likely monks threw them up as watch towers when Danish invaders pillaged the country to abolish Christianity. This one, perfectly preserved from foundation to conical cap, is 85 feet high, andstands on Devenish Island next tothe ruins of a monastery. Warring clans of Ulster and their enemies to the south used the island in Lower Lough Erne forfrequent parleys, because itslocation, surrounded by water, made a surprise attack impossible (see Color Plate V).
