ISAMBARD KINGDOM BRUNEL is famous for the engineering wonders he left behind - from the SS Great Britain to the delights of Paddington and Temple Meads stations, but much of what he designed has been lost. From the ships Great Western and Great Eastern to the majestic water towers of Crystal Palace, the Hungerford Bridge and the South Devon atmospheric railway, many of Brunel's achievements have been lost to rebuilding, fire, neglect and scrapping. What survives of some of these structures tends to be photographic or in print form, with little extant to remind us of some of Brunel's greatness. John Christopher, author of Isambard Kingdom Brunel Through Time, takes us on a tour of the lost works of Brunel, telling the story with treasures that have been lost to us, and illustrating just why Brunel can truly be crowned as Britain's most famous engineer.
