The TARDIS—which stands for Time and Relative Dimension In Space—is a traveling time machine that transports the Doctor across time and space to a wonderful array of worlds and universes. It can go anywhere at any time, harnessing the power of the Time Vortex, de-materializing in one location before reappearing in another almost instantaneously.

While the outside is stuck in the shape of an old-fashioned Police Box, the inside is a huge space of many rooms and infinite wonders!

“It’s like a Ferrari, Lamborghini and Porsche all molded into one!” says actor Matt Smith, who plays the Eleventh Doctor. “The TARDIS is a magic concept and it provides a constant source of wonderment and adventure for both the Doctor and the viewers.”
