Help

The BBC's largest drama studios in Britain officially opened on Monday in Cardiff Bay.

Roath Lock Studios is the new home for TV shows like Casualty, Upstairs Downstairs and Doctor Who.

At the weekend around 1,000 visitors took a rare peek behind the scenes of the 170,000 sq ft (15,800 sq m) site, which is equivalent to the size of three football pitches.
