ISBN 0-7185-1392-4Drawing very heavily on actually archeological excavations in the British Isles (and occassionally elsewhere) and richly illustrated with plans, drawing and photographes from the various archeological studies. This book gives a clear idea of what the evidence is for how castles were built, used and lived in. Essential for the serious student of medieval castles (not least for the extensive bibliography) it is written and illustrated in a style which makes it accessible to the general reader.
This book is still in print and readily available at around 18 pound sterling.
