at Maiden Castle and Badbury Rings but current opinion amongst archaeologists is that these, and Hod Hill, also fell with ease. There is, however, a find of 130 skeletons at Spetisbury which show that the invasion was not entirely peaceful. Dorset has many notable Roman artefacts, particularly around the Roman town Dorchester, where Maiden Castle was taken early in the Roman occupation. In the grounds of the County Council offices is a Roman house with well preserved mosaic floors and an aqueduct fed by waters of a tributary of the Frome impounded behind an earthen dam, with a covered timber-lined channel of some nine km; the dam gave way and the aqueduct was abandoned unexpectedly early, in the mid-2nd century. Roman roads radiated from Dorchester, following the tops of the chalk ridges north west to Ilchester near Yeovil, and east to Badbury Rings where it forked to Winchester, Bath and a particularly well-preserved route running north east to Old Sarum near Salisbury, as well as tracks to the many small Roman villages around the county. In the Roman era settlements moved from the hill tops to the valleys, with Roman finds, such as the famous Hinton St Mary mosaic, being found in the vales. In the Isle of Purbeck a long-settled Iron Age site at Worth Matravers was reorganised late in the Roman period to grow grain for the legion, with a grain-parching granary floor heated with a hypocaust. By the 4th century the hilltops had been abandoned. Post-Roman Although there were Jutish and later Saxon people in the Southampton area from the 5th century, the Britons seem to have successfully resisted their expansion into future Dorset for a long period. One of the key battles (Mount Badon) between the Britons and Saxons may have been fought at Badbury Rings, though this is disputed. There may have been a Saxon raid at Bindon in 614, though the location is not certain. Saxon A large defensive ditch on Cranborne Chase in the north east of the county, Bokerley Dyke, dated to 367, appears to have been fortified and - along with the blocking of the Roman Road at Ackling Dyke, to have delayed the Saxon conquest of Dorset, with the Romano-British remaining in Dorset for 200 years after the withdrawal of the Roman legions. Evidence suggests that Dorset had been largely conquered by the West Saxons by the beginning of the
