Machu Picchu

Machu Picchu  rediscovered in 1911 by Yale archaeologist Hiram Bingham, are one of the most beautiful and enigmatic ancient sites in the world. Machu Picchu stands 2,430 m above sea-level, in the middle of a tropical mountain forest, in an extraordinarily beautiful setting. It was probably the most amazing urban creation of the Inca Empire at its height; its giant walls, terraces and ramps seem as if they have been cut naturally in the continuous rock escarpments.

Heights of patience. Wonderful miniature art

Who says you can't put a camel through the eye of a needle? Russian miniaturist Nikolai Aldunin has fit seven through this one. The artist works between the beats of his heart, in order to keep his hands perfectly still. He creates works of art so tiny that a microscope is needed to see them

This is awesome

Great wall of china

The Great Wall was continuously built from the 3rd century BC to the 17th century AD on the northern border of the country as the great military defence project of successive Chinese Empires, with a total length of more than 20,000 kilometers. The Great Wall begins in the east at Shanhaiguan in Hebei province and ends at Jiayuguan in Gansu province to the west.

The wall was originally built of stone, wood, grass and earth. In the Ming Dynasty bricks were produced in kilns set up along the wall. The bricks were transported by men carrying them on their backs, donkeys, mules and even goats had a brick tied to their head before being driven up a mountain.

The Great Wall was key to protecting agriculture and resisting cavalry of the Huns and other warrior tribes from the north. The advantages of the enormous barrier diminished with the advancement of gunpowder and other weaponry.
