And If We Had To Do It Again ?

Noah built a wooden ark to save humans and animals from a great flood. Today's ships are big, but could we build one big enough to save the world?

The Brooklyn Bridge in New York is one of the most imposing bridges in the world and its construction has caused many accidents. Experts use the latest technology and modern science to reveal if building it a second time would be safe.

The Great Pyramid of Cheops, a symbol of Egyptian antiquity, is the largest and oldest pyramid in Giza. It is one of the 7 wonders of the world still standing today. It contains the forgotten secrets, history and know-how of the ancient Egyptians. 4000 years after its construction, it looks like a huge pile of stone. With the help of the most efficient machines, the most sophisticated technologies and the money necessary to build the pyramid of Cheops today , we will oppose modern tools to ancient techniques and challenge the skepticism of the greatest experts. But would we still be able to build the Pyramid of Cheops today?

The Great Wall of China is one of the 7 Wonders of the World, and to build it you had to take risks and use your imagination. Experts use the latest technology and modern science to reveal if building it a second time would be possible.

Rome, 1st century AD, the capital of an empire that dominates Europe. Its greatest technological achievement: ACCESS To running water. The water supply system in Rome is one of the greatest wonders of Antiquity. The Roman aqueducts transported nearly 750 million liters of water per day to a city of one million people. This system still rivals the sewerage systems in large cities today. In a time of global warming, water has become a precious commodity and experts are sounding the alarm, but are our engineers living up to their Roman predecessors? And if we had to do it again, would we still be able to build the aqueducts of Rome?

The Pantheon, a temple built almost two thousand years ago, is an extraordinary monument. It has survived the ages in practically intact condition and its dome, built with more than 4,500 tons of concrete and measuring 43 meters in diameter, shows no signs of weakness. This architectural and engineering feat calls into question our current know-how: would we be able today to reproduce such a masterpiece?

The Colosseum is the largest building built by Rome. Its grandiose architecture testifies to the genius of the builders of the time. Able to accommodate up to 50,000 spectators, it had a “removable” roof, a level floor, water fountains, elevators, drainage systems and pipes. Would current engineering and architectural techniques allow this record-breaking construction to be reproduced identically?

Venice is a city in crisis with devastating floods. Experts then use the latest technology and modern science to reveal if building it a second time would be possible.
