One interesting point of this book is the influence of Moslem fortifications on Europe, especially Italy and Iberia.  For those willing to make the effort, this book offers an insight into European fortifications before and during the introduction of gunpowder.

The author covers the wide array of fortifications built in the Middle East and the Indian subcontinent by the Sljuks, Ayyubids, Mamluks, Mongols, Timurids... For those interested in the military history of the regions covered, this book makes an excellent illustrated reference at an introductory level.

Overall, a fascinating look at these ancient constructs and how they fared over the years. As with other Osprey titles, this is one that I know you will enjoy reading.
