The Vertigo Tour was a worldwide concert tour by the Irish rock band U2. Staged in support of the group's 2004 album How to Dismantle an Atomic Bomb, the tour visited arenas and stadiums between March 2005 and December 2006. The Vertigo Tour consisted of five legs that alternated between indoor arena shows in North America and outdoor stadium shows internationally. Much like the previous Elevation Tour, the indoor portion of the Vertigo Tour featured a stripped-down, intimate stage design. Protruding from the main stage was an ellipse-shaped catwalk that encapsulated a small number of fans.
