A street in north-west Wales has been crowned the world's steepest. Ffordd Pen Llech in the historic town of Harlech has a gradient of 37.5% at its steepest point, knocking Baldwin Street in Dunedin, New Zealand, off the top spot. Gwyn Headley, who led the town’s campaign to claim the title, said: 'I feel utter relief and jubilation. I feel sorry for Baldwin Street and the New Zealanders, but steeper is steeper.'
