Egypt's Great Pyramid may be humanity's greatest achievement: a skyscraper of stone built without computers or complex machinery. This super-sized tomb has fascinated historians and archaeologists for centuries, but exactly how the ancient Egyptians finished the monument and fitted its two and a half million blocks in a quarter of a century has long remained an enigma. Today the secrets of the pyramid are finally being revealed thanks to a series of new findings. At the foot of the monument, archaeologists are uncovering the last surviving relic of the pharaoh Khufu, whose tomb it is: a huge ceremonial boat buried in flat-pack form for more than 4500 years. It's a clue that points to the important role that ships and water could have played in the pyramids' construction. This documentary follows investigations that reveal how strong the link between pyramids and boats is. It's a story of more than how Egypt built a pyramid: it's about how the pyramid helped build the modern world.

The Channel Tunnel linking Britain with France is one of the seven wonders of the modern world but what did it take to build the longest undersea tunnel ever constructed? We hear from the men and women, who built this engineering marvel. Massive tunnel boring machines gnawed their way through rock and chalk, digging not one tunnel but three; two rail tunnels and a service tunnel. This was a project that would be privately financed; not a penny of public money would be spent on the tunnel. Business would have to put up all the money and take all the risks. This was also a project that was blighted by flood, fire, tragic loss of life and financial bust ups. Today, it stands as an engineering triumph and a testament to what can be achieved when two nations, Britain and France put aside their historic differences and work together.
