DOCTOR WHO'S TARDIS SPENDING CHRISTMAS AT CAERPHILLY CASTLE

After travelling through time and space Doctor Who's Tardis has landed at Wales' largest medieval castle.

The blue police box which is located on top of the Inner East Gatehouse tower is lit up during the night and will stay there until the New Year.

The castle was used to film some scenes for the two part Christmas episode of Doctor Who, entitled The End of Time.

On December 12 and 13th, visitors to the Medieval Christmas fayre at the castle would have seen the unusual spectacle as they did their Christmas shopping and enjoyed the festive entertainment supplied by jugglers, jesters and stilt walkers.

Tardis stands for Time and Relative Dimension in Space - the machine has been the chosen mode of transport for all of the ten Doctors on their intergalactic adventures.

The End of Time is the final journey for the tenth Doctor, played by David Tennant, as he prepares to do battle with his nemesis, the Master.

Doctor Who - The End of Time Part One is on BBC One Wales at 1800 GMT on Christmas Day with Part Two is on BBC One Wales at 1840 GMT on New Years Day
