Roald Dahl Plass

Roald Dahl Plass was a large public square, part of the Cardiff Bay district of Cardiff, Wales. It was a poorly-kept secret among many Cardiff residents that somewhere near the Plass was the site of Torchwood Three's headquarters. TW: Children of Earth: Day One)

Behind the scenes

 * In real life, the fact that Doctor Who and Torchwood have so prominently featured the Plass has made it a popular destination for fans visiting Cardiff. It is also one of the more public filming locations, so whenever the Doctor Who and Torchwood crews film there, it often attracts media attention (such as on 6 January 2010 when filming for Series 5 of Doctor Who took place there .)
