"Collection of maps and places of Hue Citadel" provides readers with an extremely large amount of information about Hue Citadel through a huge map system collected by two authors Henri Cosserat and Leopold Michel Cadiere. The author not only presents us with each image of each map, but also includes an accompanying analysis. The 28 maps are arranged in order of time of appearance and are fully introduced from their origin (time, source, place of first publication...) as well as their meaning and necessary application.
