Ritz Tower
From Tardis Wiki, the free Doctor Who reference
Ritz Tower was a hotel overlooking Cardiff Bay. It was built by Bilis Manger to harness the power of human aggression in order to open the rift and send a message to whoever the Sorax fled from, wanting them out of Cardiff. When Sandra and Andrea tried to kill Colin Colchester-Price, Mr Colchester killed them, allowing Bilis to send his message. (AUDIO: A Kill to a View)
