The military history of Gibraltar is complex and varied, lying as it does at the gateway to the Mediterranean and the meeting points of the continents of Europe and Africa. From the Islamic invasions of Spain in the 8th Century to the base for Mediterranean Task force H in World War II, 'the Rock' has played a significant part in the military history of Europe over hundreds of years. Yet, Gibraltar is not only a prime example of a fortress, but it also contains a unique record of the evolution of fortifications and associated defences spanning over six hundred years. This book covers the fascinating history of the fortifications on Gibraltar and the development of the sites into what they are today.
