Abbotsbury Castle is an Iron Age hill fort in south west Dorset, England, situated on Wears Hill above the village of Abbotsbury, seven miles west of Dorchester and the famous hill fort at Maiden Castle. The fort was occupied by the Celtic Durotriges tribe and was situated on a high chalk hill overlooking the English Channel, making it the front line of defence from invasion. When the Romans did invade in AD 43, the second Augustian legion of Vespasian took the fort quickly with little struggle before moving on to Maiden Castle.
