Valhalla was the afterlife in Norse mythology.

When Beowulf saw the black TARDIS materialising, he believed that its doors were the gates of Valhalla. (AUDIO: Black and White)

The Tenth Doctor was taken to a recreation of Valhalla on board a spacecraft. (COMIC: Space Vikings!)

Princess Freydis asked the Eleventh Doctor if the TARDIS was Valhalla. (PROSE: Dark Horizons)
