The Idea of the Castle in Medieval England by Abigail Wheatley [Repost]

From reading this book it is clear that what we mean by the term `castle' today is not the same as the medieval concept of what a castle was. Approaching castle architecture as a historian would approach ecclsiastical architecture, Abigail Wheatley argues that the castle was deeply ingrained within medieval culture and it had a much wider meaning beyond the obvious feat of military engineering.
