The 1960s cult TV series, "The Prisoner", was largely shot where?

Portmeirion is a tourist village in Gwynedd, North Wales. It was designed and built by Sir Clough Williams-Ellis between 1925 and 1975 in the style of an Italian village, and is now owned by a charitable trust.

In 1966–1967 Portmeirion was used to film exteriors for The Prisoner, a surreal spy drama in which Portmeirion played a starring role as "The Village", in which Patrick McGoohan's retired intelligence agent, known only as "Number 6", was incarcerated and interrogated, albeit in pleasant surroundings. At Williams-Ellis' request, Portmeirion was not identified on screen as the filming location until the credits of the final episode of the series, and indeed, Williams-Ellis stated that the levy of an entrance fee was a deliberate ploy to prevent the village from being spoilt by overcrowding. The show, broadcast on ITV in the UK during the Autumn of 1967 and CBS in the United States in the Summer of 1968, became a cult classic, and fans continue to visit Portmeirion, which hosts annual Prisoner fan conventions. The building that was used as the lead character's home in the series currently operates as a Prisoner-themed souvenir shop. Many of the locations used in The Prisoner are virtually unchanged after more than 40 years.
