Books about the Middle Ages, medieval castles and towns are numerous. Even more numerous are the books, brochures, leaflets and articles concerning local fortifications. Because it is impossible to enumerate all publications, I shall list below only a subjective selection of a few works particularly relevant, useful and interesting, in the hope that they may provide sources of further reading.
