Martello Towers Worldwide follows the history of the Martello tower from the construction of the early towers built to protect the Mediterranean shores of Spain and Italy right up to the final towers built in the United Kingdom during the First World War. The book is illustrated with a large number of contemporary and historic photographs, drawings and plans, a very large number of which were not included in the earlier Towers of Strength. These provide the most detailed information yet published about the development of the Martello towers in Britain and overseas. So the book will be of particular interest to those interested in the history of fortifications, architectural conservation and military history generally. It will also be of interest to an international readership as the book now has a gazetteer of towers outside the United Kingdom that remain today together with a chapter describing a number of towers built in the United States. The book supplements the earlier Towers of Strength and such will be an important addition to the existing bibliography of books on Martello towers and fortification.
