This is the eighth in the Department’s archaeological monograph series. Manning oversaw the survey and excavation, including an underwater investigation, of the castle in 1987 and has now been enabled to bring this thorough report into print. The different sections of the book consider the setting of the castle, its history, description, conservation and excavation. A sixth section contains the specialist reports on various aspects of the archaeology, such as bone objects, military artefacts and textiles, while the final section is an informative and thought-provoking discussion on the results of the excavation and investigation and their significance in the local and national context.
