The white heat of the technological revolution...the high point of British architectural modernism. The 1960s was the age of Big Tech. It took a machine the size of a bungalow to do what a palmtop can do today. Our surroundings were dramatically changed by transmitter masts, listening stations, radio telescopes and sculpturally audacious buildings. These monuments of a distant age are tracked down with the help of a Bennometer, named in honour of Harold Wilson's Minister of Technology, Anthony Wedgwood Benn (as he then was).
