Work to preserve the crumbling birthplace of radar is to get under way in a year that marks its 80th anniversary.
The first fully operational radar station in the world was set up in Bawdsey, Suffolk in September 1937.
A £1.4m lottery grant will finance major construction work, starting in September.
It was part of RAF Bawdsey near Felixstowe, and it is acknowledged as playing a major role in Britain’s aerial battle against Germany in World War Two.
It is estimated that 4,000 personnel served at RAF Bawdsey between 1938 and 1945.
