Great wonders of the modern world: the Colosseum, the Egyptian pyramids, Hadrian's wall, Tower bridge, the Eiffel tower, the Golden Gate bridge, the Trans-Siberian railway and the Empire State building

This programme journeys back in time to take an in depth look at Rome's mighty Colosseum, an architectural masterpiece that still inspires awe after 2,000 years. The Egyptian Pyramids were constructed as tombs for the ancient pharaohs, over 100 pyramids remain in Egypt. Built during a span of over 1,000 years, they stand as cultural and engineering marvels of staggering proportions. Hadrian's Wall is 74 miles long and 2,000 years old, Hadrian's Wall winds over the hills and valleys of Northern England, marking the northernmost extent of a once mighty empire. Built of stone and mortar, Hadrian's Wall stands in mute testament to its long-ago builders and is a tantalising treasure that still holds many secrets archeologists and historians are eager to uncover.

Tower Bridge was built at the same time as the Statue of Liberty and the Eiffel Tower, London's Tower Bridge quickly became an icon of its nation, a symbol of industrial might and technological daring combined with a deep sense of tradition. This programme ventures from the Victorian era to the present day to tell the complete story of this famous bridge. The Eiffel Tower was meant to be a temporary exhibit, a demonstration of French engineering acumen at the Paris World Fair. But to Parisians, the tower, designed by the brash, young Gustave Eiffel, came to stand for much more. This is the monumental tale of the graceful steel sculpture that stands at almost 1,000 feet.
