Join us on Expedition Extinct as we look at the one year Millennium Dome Experience to celebrate the third century in the year 2000. This odd mix of museum and theme park received huge amounts of criticism before, during and after the event and ended up one of the weirdest most expensive sponsored exhibits ever created. Planned to be the first wonder of the 2000's it will ultimately a huge failure. Later it was reborn as the o2 Arena and Dome and the original experience was forgotten.
