Poundbury Camp is situated on a bluff of the Upper Chalk overlooking the river Frome and its water-meadows (pl. LXVII). The approach from the south and west slopes gently riverwards, but to the east the site is separated from the outskirts of Dorchester by a shallow combe. Though its situation is hardly that of a hill-fort, usually isolated on a detached hill or promontory, nevertheless the camp holds a commanding position in relation to its immediate surroundings, and its multiple defences, now sadly defaced, must once have presented a considerable obstacle to enemy attack. Though not comparable in size to the oppidum of Maiden Castle, for it encloses an area of only 15 acres, the existence of such a stronghold less than two miles distant from the major hill-fort seemed to require investigation. By whom had it been constructed, for what purpose, and to what extent had it been occupied, were questions demanding explanation. It was with the intention of bringing some light to bear on these problems that excavations were carried out at Poundbury in the spring of 1939.
