Perched on an isolated rock in the Scottish Hebrides, this is a fascinating account of Skerryvore, 'the most graceful lighthouse in the world', and the great Victorian engineer who designed and built it. At a height of 48m (156 feet), it is the tallest lighthouse in Scotland. The story of the Skerryvore lighthouse and its creator, Alan Stevenson, is remarkable by any standards. Here was a man of exceptional intelligence and wide-ranging ability who overcame Herculean challenges over a six-year period to place a lighthouse on an isolated rock in the wild North Atlantic, 12 miles off the Hebridean island of Tiree. He was a brilliant and complex character, much loved by his family and those who knew him, but beset with self-doubt. His is a moving and truly amazing story just waiting to be told.
