We are indebted to the Saxons but for few social improvements; since, in the words of the Wiltshire antiquary, John Aubrey, "They were so far from having arts, that they could not even build with stone. The church at Glaston (bury) was thatched. They lived skittishly in their houses, they ate a great deal of beef and mutton, and drank good ale in a brown mazzard, and their very kings were but a sort of farmers. The Normans then came, and taught them civility and building." In various parts of England, Scotland, Ireland, and Wales, there are numerous encampments or castles, mostly occupying the summits of hills, which have been ascribed to the aboriginal inhabitants. Amongst the most remarkable are the Hereford Beacon, on the Malvern hills, in Worcestershire; the Caer-Caradock, near Church Stretton, in Shropshire; Moel Arthur, in Flintshire; Chun Castle, in Cornwall; and the magnificent hill-fort, Maiden Castle, or the Castle of the great Hill, within three miles of Dorchester. Maiden Castle had four gateways of stone; in excavations have been found round stones, probably sling stones, and pottery, denoting its original occupation by Britons; how the fortress was supplied with water has not been traced. This famous earthwork is considered of a period anterior to that of the Britons and Romans: the extent of the work is one mile, and the ramparts are, in some places, sixty feet high. Another famous earthwork in Dorset is Poundbury, a Roman encampment, though it has been set down as Danish, and an Anglo-Saxon camp of council.[22]
