IIaruham Camh. ANCIENT EARTHWORKS Compared with hill-top camps the rectangular Roman camps present many striking differences. One of the chief of these is that whilst the earlier works occupy the whole of the available hilltop, the Roman works are limited in area and restricted in shape, being con- structed, not with reference to site, but with ^^ reference to requirements. Again, the pre- historic works are situated, almost invariably, upon the highest summits of the hills, in positions frequently remote from water and sources of fuel, whereas the Romans seem always to have made a point of constructing their camps on level ground, and within easy reach of both fuel and water. The number of the prehistoric camps, moreover, is much in excess of those which are known to have been occupied by the Romans. Further, prehistoric camps occasionally contain traces of hut- circles, whilst the Roman camps do not contain them. The method ot defending the entrance to the earlier camps, and the flint implements with which neolithic camps are generally associated, present striking contrasts to the Roman camps. In the present condition of knowledge of early earthworks it is impossible to be certain as to the characteristics of Bronze Age camps and Prehistoric Iron Age camps, but as far as one can judge from the available evidence, Sussex does not contain any example which could be referred without doubt to either of these periods. Still, there is evidence that HoUing- bury Camp was used during the Bronze Age and Mount Caburn during the age of pre- historic iron. Sussex possesses two walled fortresses or towns of undoubt- edly Roman origin, namely Chichester and Pevensey, and there are earthworks of an in- teresting character in connec- tion with both. Chichester. — The pre- sent town walls are largely of Roman construction, or on Roman foundations, and they are backed by a rampart, parts of which still remain. Some distance to the north of Chichester is an outwork of rampart known as ' The Broil,' consisting of two sides of a square said to be each a mile in length, but not now entirely visible. 471 ICHESTER.
