Cold War Bunkers is the third volume in a series of high-quality photographic records of Britain's underground heritage. Other volumes in the series cover the wide range of underground structures built during an in preparation for the Second World War, and also the surviving relics of the world-famous subterranean stone quarries of the Bath and Corsham areas of the West of England.
Each of the large-format volumes contains approximately 450 colour and B&W archive photographs accompanied by comprehensive captions, an authoritative text and, when neccessary, supporting maps, plans and diagrams.
In many instances Nick Catford has been granted unprecedented access to many highly sensitive sites in order to compile the collection of photographs reproduced in this book.
From the Publisher
Cold War Bunkers is a comprehensive photographic overview of all the underground, semi-underground and surface-built cold-war atomic and nuclear bunkers built in the British Isles to protect central, regional and local government, military organizations, the Civil Defence organization, the Royal Observer Corps, UKWMO and the public utilities against nuclear attack by the Soviet Union between 1946 and 1989.
Amongst the sites represented in this volume are:
the Corsham Central Government War Headquarters (Burlington); the Regional War Rooms built during the early 1950s and the network of Civil Defence bunkers that supported them; the Regional Seats of Government (RSGs) of the 1960s, the SRHQs that were built at the end of that decade and into the 1970s, and the highly sophisticated and hugely expensive Regional Government Headquarters of the 1980s.
Also covered are the huge range of ROC bunkers from the very large Sector Controls to the tiny 3-man observation posts; the often complex and sometimes Spartan County and District council bunkers, bunkers built by the water companies, and the deep underground emergency telephone exchanges built by the GPO and BT.
The book also goes in great detail into the underground radar control rooms established as part of the RAF's 'Rotor' radar system and also the hardened anti-aircraft gun control rooms which were integrated with 'Rotor' in the early 1950s.
Coverage is also given to the cruise missile site at Greenham Common along with many other sites and structures too numerous to mention.
For some reason, the three books appear to be being released in reversed order, ie third volume first, then second and finally first... ::)

...the third volume covering the history of the Bath and Corsham stone quarries up until the start of the Second World War will follow shortly.
