historically, anglesey has long been associated with the druids. in ad 60 the roman general gaius suetonius paulinus, determined to break the power of the druids, attacked the island using his amphibious batavian contingent as a surprise vanguard assault and then destroying the shrine and the nemeta (sacred groves). news of boudica's revolt reached him just after his victory, causing him to withdraw his army before consolidating his conquest. the island was finally brought into the roman empire by gnaeus julius agricola, the roman governor of britain, in ad 78. during the roman occupation, the area was notable for the mining of copper. the foundations of caer gybi, a fort in holyhead, are roman, and the present road from holyhead to llanfairpwllgwyngyll was originally a roman road. the island was grouped by ptolemy with ireland ("hibernia") rather than with britain ("albion").
