Entitled as it is, it deals with the mysteries and marvels of Mughal Architecture which the author came across during his study of this subject, for nearly half a century. The various aspects of Mughal architecture are uncommon and unique, and are not present in any other architecture. They are simply wonderful. They evoke innocent curiosity and make their history more interesting than fiction. In all, 155 plates (including digital images), 84 figures (drawing of plans, sections and elevations) and 5 Persian inscriptions and texts have been used to illustrate these mysteries and marvels.
