Isambard Kingdom Brunel's colossal ship, the Great Eastern, is the only wonder described here that has not survived to the 21st century. In the early 1850s, Brunel hoped the ship would be his masterpiece, and that it would provide an enduring link to even the most farflung parts of the empire. At a time when most ships moored in the Thames were built to traditional designs in wood, and powered by sail, Brunel's 'Great Ship' was almost 700 feet long, a floating island made of iron. His vision was that it should carry 4,000 passengers, in magnificent style, as far as the Antipodes - without needing to refuel.
