Torchwood Wrexham

Torchwood Wrexham and Torchwood Wrexham Bypass were nicknames given by Gwen Cooper to a Torchwood cache hidden inside a slag heap. It was accessible by a biometrically-coded portal disguised as a rock shaped like a heart.

Five years after Miracle Day, Gwen and Rhys Williams went there to get a bio-stabiliser for Jack Harkness, who had been transferred by the Evolved into the ageing body of Mr Griffith. (AUDIO: Forgotten Lives)
