Presenter Rob Bell takes us on a voyage around Britain and Ireland to reveal the hidden secrets that make offshore lighthouses such extraordinary feats of engineering.
"Rob Bell explores the historic but deadly southwest coast of England to discover what made the world's first rock lighthouse on Eddystone reef such a monumental achievement over 300 years ago."
"Rob Bell explores the rugged east coast of Scotland to discover how the Bell Rock lighthouse earned its reputation as a wonder of the industrial world."
"Rob Bell looks at the construction of more rock lighthouses, beginning with Wolf Rock - 8 miles off the Cornish coast. He discovers the feat of Victorian engineering required to build the structure against the power of the Atlantic Ocean."
"From stormy seas to the land-locked Mojave Desert, Rob Bell discovers the amazing story of how the mighty Colorado river was tamed and the Hoover Dam built."
"Rob travels the Panama Canal to learn how the seemingly unconquerable isthmus was bent to the will of determined engineers, creating one of seven wonders of the new world."
"Rob heads to England's south coast where he explores a trio of lighthouses built to protect vessels. He also experiences gravity-defying Victorian innovation."
