Architect Mark Fisher reveals U2's plans to give their stages away
U2 are hoping to turn the stages from their current world tour into permanent concert venues in parks around the world when their tour is over.
The band's current 360 tour uses three different stage structures, each in the shape of a giant claw.
"My vision, which I've been discussing with the band, is that we will turn them into concert pavilions," their tour architect Mark Fisher said.
The band play their first UK date at Wembley Stadium in London later.
The tour then moves to Glasgow, Sheffield and Cardiff.
U2 have already played in Europe and will travel to the US next month.
Mr Fisher said three steel structures, which cost between £15m and £20m each, were used on different legs of the world tour.
"Part of the tour will finish in Australia and another part of the tour will finish in South America, where people could use a nice concert pavilion in a park, which has an ability to take 200 tonnes of kit hanging under it," he said.
