Rockers U2 have angered environmentalists in Ireland with plans to build an unsightly skyscraper in Dublin. Building heritage group An Taisce has criticised the group for its plans to demolish the Clarence Hotel - which the band owns - and redevelop the site through a $200million (GBP100 million) investment programme. The organisation has called for an investigation into the so-called 'U2 Tower', which is set to be the tallest building in Ireland. Ian Lumley of An Taisce, says, "Our biggest concern is that the U2 Tower will stick out of the skyline from parts of Georgian Dublin. It could potentially be an incongruous blot on the skyline on the south side of the city." Lumley also claims the band has ignored the impact of climate change on the proposed building - which could be affected by rising sea levels due to its position at the mouth of Dublin river.
