The Great Wall stretches for 4,160 miles across North China. It is the only man-made structure that can be seen from the moon with the naked eye. Its construction started as far back as the Spring and Autumn period (770-476 B.c.) and the Warring States period (475-221 B.C.). Rival feudal kingdoms built walls around their territories to keep out invading nomadic tribes from the north. When Qin Shihuang unified China, he started to link up and extend these walls. Prisoners of war, convicts, soldiers, civilians and farmers provided the labor. Millions died for this cause and many Chinese stories speak of parted lovers and men dying of starvation and disease. Their bodies were buried in the foundations of the wall or used to make up its thickness. The Great Wall crosses loess plateaus, mountains, deserts, rivers and valleys, passing through five provinces and two autonomous regions. It is about 20 feet wide and 26 feet high. Parts of the wall are so broad that 10 soldiers can walk abreast. Materials used were whatever could be found near by-clay, stone, willow branches, reeds and sand. Parts of this wall can still be seen in remote parts of China. What most visitors see of the Wall now was restored in the Ming dynasty, when stone slabs replaced clay bricks. It took 100 years to rebuild and it is said that the amount of material used in the present wall alone is enough to circle the world at the equator five times.

The Taj Mahal (Crown Palace) is India's most famous structure, and, perhaps the most beautiful piece of architecture in the world. Photographs cannot truly capture its grandeur. While this is true for most photos, it seems especially true for this almost perfectly proportioned tomb of Mumtaz Mahal and its creator, Shah Jahan, the fifth Mughal ruler,

Taj Mahal stands on the bank of River Yamuna, which otherwise serves as a wide moat defending the Great Red Fort of Agra, The Taj rises on a high red sandstone base topped by a huge white marble terrace on which rests the famous dome flanked by four tapering minarets. Within the dome lies the jewel-inlaid cenotaph of the queen. So exquisite is the workmanship that the Taj has been described as "having been designed by giants and finished by jewellers". The only asymmetrical object in the Taj is the casket of the emperor which was built beside the queen’s as an afterthought. The emperor was deposed by his son and imprisoned in the Great Red Fort for eight years but was buried in the Taj. During his imprisonment, he had a view of the Taj.

Mount Everest or Sagarmatha or Chomolungma is the highest mountain on Earth, as measured by the height of its summit above sea level. The mountain, which is part of the Himalaya range in High Asia, is located on the border between Nepal and Tibet.
