Earthwork Castles of Gwent and Ergyng AD 1050-1250
University of Wales, 2005
This thesis is concerned with the earthwork and timber castles built in the southern March of Wales between the periods AD 1050-1250. The research addresses the presence of the castles and discusses their roles as weapons of conquest and structures of administrative control. It is argued that the recognisable change in the form of earthwork castle construction over the 200 year period can be seen as a consequence of changing functions. Although it has not been possible to demonstrate how the area within a castle was used, it has been possible to identify a difference in the degree of defence verses habitation space associated with these structures.
