This August sees the 70th anniversary of the dropping of the atomic bomb on this city from the US bomber named Enola Gay. There is now a Peace Park at the site under where the weapon was detonated 600m above the city. The museum has a scale model where the bomb is represented as a small ‘sun’ – which in some respects it was – exploding in the air at 8.15am on the morning of 6 August 1945. There will no doubt be ceremonies to mark the anniversary of this ghastly event, which in many ways sadly marks the advent of ‘the nuclear age.’
