Mona, now known as Anglesey in Wales, was storied to be the home of the Druids as mentioned in accounts by Julius Ceaser. In AD 60, the Romans under Suetonius Paullinus, decided that it was vital to invade Anglesey and destroy the power of the Druids. The Romans eventually won the battle and destroyed the Druids on Anglesey and cut down their groves of sacred oaks.
