It was 50 years ago, on 5 September 1966, that the cameras rolled for the first time in the Italianate village of Portmeirion* as filming got under way for the cult 1960s adventure TV show The Prisoner.
The programme starred actor Patrick McGoohan playing the part of Number Six who is held captive in a mysterious village where the residents are known only by a number.
Each week, he would attempt to escape, only to find himself unable to break free from those who held him. But who were they? Why was he imprisoned? Which side were his captors on? And who was Number One?
