The Millennium Dome project in London was an ambitious government project intended to celebrate mankind's achievements at the turn of the new millennium, but ultimately failed due to poor planning and execution. The project concept was championed by Prime Minister Tony Blair, but it was poorly managed from the start with politicians rather than business professionals driving the vision. The Dome received heavy criticism for its lack of clear themes and content. While projections estimated 12 million visitors, only 6.5 million actually attended, far below what was needed to recoup the total costs of £789 million. Contributing factors to its difficulties included a lack of proper vision, unrealistic expectations, and failure to properly plan for its post-event use and management.
