The Millennium Stadium was a venue in Cardiff, Wales. It was built in 1999 and replaced the old Cardiff Arms Park. Jack Harkness noted that the new stadium was built at a 90 degree angle to the old one, which aligned it with the Cardiff Rift. (PROSE: Pack Animals) It was used for the last live performance of the rock band Unattended Article in 2000, which was hijacked by the Mondegreens. (COMIC: We Will Rock You)
