Karen Gillan: We’ve been filming here all week. It’s our last day of filming. It’s called Caerphilly Castle in Caerphilly. What they didn’t tell us while we were filming is that it’s in fact haunted.
David (Ghost Tour Guide): Caerphilly Castle is haunted by the ghost of the Green Lady. And the story goes back to 1268.The castle was founded by a man called Gilbert de Clare, or Gilbert the Red, who had a lovely wife called Alice. And she fell in love with a local Welsh prince. Gilbert was so upset about this, he banished her back to France. And he had the local Welsh prince killed. When she heard the news, she dropped down dead. Literally dying of a broken heart.
