Cardiff Bay was the district of Cardiff where Roald Dahl Plass and the Hub, the base of Torchwood Three, were located. The Rift was located above it. Torchwood Three also possessed a secret dock leading into Cardiff Bay which, until 2009, contained a small ship called the Sea Queen. (AUDIO: The Sin Eaters) The Sea Queen was replaced by the Sea Queen II. There was also a submarine, but it had been lost between 1970 and 2009. (PROSE: Risk Assessment)
