This, the second volume of an Inventory of the earthworks of Northamptonshire, describes the
archaeological sites within the central part of the county. In this area, no less than in that covered
by the first volume, ploughing, ironstone-mining, gravel-quarrying and urban development continue
to present a threat to many of the sites. Of the 770 or so monuments which are described, many
have not hitherto been recognized.
The archaeological sites recorded in this volume have been examined by our staff, but much
original material was gathered from published records and manuscript notes and from verbal information supplied by local archaeologists and historians; the Commission is conscious of the debt
which it owes for the help received from these sources. It is hoped that this Inventory will be of use
not only to archaeologists but also to those concerned with planning decisions or with conservation.
