"Battleship Islands: Alderney" is the first episode of an on-going series about fortified islands, and it focuses on the amazing fortifications of the third largest of the English Channel Islands. Produced with extensive research on the subject, it features a populist approach to appeal to both military buffs and the general public. This presenter-led, authored documentary encompasses all the main historical and technical aspects of the defence works still visible on Alderney, which was a fortified base for the Royal Navy in Victorian times and occupied by the German army during World War Two for longer than anywhere else. It was a crucial part of the Atlantic Wall and became its most densely defended stretch, with a dark and often unknown side to its fortifications. There are also some surprising remains from earlier times. It features explorations of the fortifications, explanations with the aid of local experts and animations, plus relevant archive footage and pictures, for a narrative that will intrigue viewers and add unexpected interest to bunkers and forts, with an engaging photography to illustrate the Island’s natural beauty.
