The Teutonic Knights were the most warlike of the religious orders, and this is reflected in the architecture they left behind. The Teutonic memorials are the magnificent castles they built as a result of their conquest of Prussia. They were all built of brick, and raised during a period of less than a century and a half between 1230 and 1380. Many of these dramatic fortresses still exist today in what is now Poland, and provide a unique example of an architectural style that is both well defined and very closely reflects the nature of the men who created it. This book details the history of these spectacular fortresses from their inception through to their eventual decline and fall.
