The exterior of Lady's Lodge was used to represent the General Store in The Prisoner.
The interiors were filmed in the studio.

The location was used for the filming of the cult 1967 British television series "The Prisoner",
starring Patrick McGoohan. Visitors to Portmeirion over the Convention weekend can watch outdoor activities,
but not attend indoor events. To join "Six of One", see the Information page, or click the link at the top of this page.
With the backing of Carlton International Media, owners of the series, and Portmeirion, who operate their famous "Prisoner Shop",
Six of One recreates the ominous "Village".
From here, in the 17 TV episodes, the prisoner 'No. 6' tried each week to escape.
Open buggies, giant white 'guardian' balloons, penny farthing bicycles and strange characters
made up the fantasy Village. Join in the proceedings - from carnival atmosphere,
to serious debate; from enactments, to screen presentations;
from games like "Human Chess", on a large lawn board, to celebrity guests.

The series' unforgettable catchphrase is: "Be Seeing You!"
