The Second Great Battle of Jericho

It's the most extraordinary feat of engineering in history, and one of the most iconic man-made structures on the planet - the Great Wall of China, stretching thousands of miles across barren deserts and treacherous mountains before finally plunging into the sea. But why did the Chinese go to such staggering lengths to build it, and what are the secrets that have enabled it to survive for over 2,000 years? Now, ground breaking science is re-writing its complex history and de-coding its mysteries to reveal that there is much more to the Great Wall than just bricks and mortar. Cutting edge chemistry reveals that the secret to the Great Wall's remarkable strength is a simple ingredient found in every kitchen, and a new survey also determines that its length is truly amazing, as we finally solve the enigma at the heart of the world's greatest mega-structure.

Huelva, Spain, an isolated region lost in time. The grass, the sand and the sky are the same that those foreigners saw in the spring of 1895, when they crossed the sea from a distant country to mark the unspoiled terrain and extract its wealth, when the tower was new, when people could climb to the top of the highest dune and imagine that the city of Tartessos was still there, in the distance, almost invisible in the morning brume.

With an area three times larger than Pompeii, Baia, about 15 km from Naples and within the volcanic area of the Phlegraean fields, is the largest underwater archaeological site in the world.
