Passage: The Poole Harbour area has been inhabited for at least 2,500 years. During the Iron Age, Celtic people known as the Durotriges lived in Dorset, particularly around Wareham, fivemiles (8km) to the west. In the 3rd century BC, these Celtic people moved from hilltop settlements, such as Maiden Castle and Badbury Rings on the chalk downs to the north, to the lower vales and heathland around the River Frome and Poole Harbour. This marshy area may have lent its name to the Durotriges, which means "water dwellers". The Durotriges engaged in cross-channel trading at Poole with the Veneti, a seafaring tribe from Brittany. The earliest significant archaeological find in the harbour is the Poole Logboat, a boat made from a single oak tree and dating to 295 BC. During that time, the harbour was shallower than it is today and any settlement would now be under water.
