By Mark Jones The Great Wall has changed dramatically over the millennia.
Its shape, architecture and history have all changed over the centuries, but its importance has not.
It is now a vital part of China’s economy and culture.
The Chinese government is currently planning to extend the length of the wall to 4,500km (2,700 miles), and to build a third ring to the south.
These developments will make it possible for China to reach a larger and more diverse population than it has ever before.
But this new frontier is being built at great expense, and the cost is borne by China’s poor and vulnerable people.
The Great Barrier Reef has been lost over the last few decades, and even the world’s largest mangrove forests in Indonesia have been devastated by a warming climate.
But the Great Barrier and its tributaries have been a symbol of China for millennia, and its future lies in the future.
Today, the wall has become a monument to a country’s past, an icon of Chinese civilisation, and a reminder of China being the “new world” and the “world of the future”.
In this programme, we talk to conservationists and scholars about the Great, and how its construction and destruction has affected the planet.
We’ll hear from the head of the International Union for Conservation of Nature (IUCN), who is urging China to abandon the wall and re-establish it in the interest of its people.
We will also see the effects of the Great Seal of China, a symbol that was created by the British government in order to protect British imperial history from becoming a museum for the world.
We meet with the world-renowned Chinese expert, Professor Yang Zhenqiu, who has written a book about the history of the Chinese seal.
He has also written a new book on the Great wall, which is due to be published next year.
We also meet with an artist who has painted and restored the Great barrier.
This is the first programme on the subject, and it’s part of BBC World Service’s World History series.
Listen to this programme The Great wall of China The Great and the Beautiful The wall, a monument built by the Chinese Emperor in 1268, is the oldest surviving structure on earth, dating back to the time of the Han Dynasty.
The structure is divided into a Great Wall and a lesser Wall.
The wall is built along the east coast of China to protect the land from the threat of invading invaders, and to prevent people from invading the north.
But when the Great Emperor died in 1281, it was divided into three parts: a Great Gate and a Great Dome.
These are the two largest sections of the building, which are built over an area of about 25,000 square kilometres (8,000 sq miles), covering an area that is more than twice the size of South Africa.
The outer perimeter of the great wall is called the Great Gate.
It’s a long rectangular structure that spans nearly 2,000 metres (96 feet) and is topped by the Great Dome, a curved, six-metre-high (20-foot) structure that stands at the centre of the entire wall.
This dome is made of stone, and is about 15 metres (49 feet) tall.
In addition to the Great Door, the Great and Great Domes are also built over a long expanse of land known as the Great River Delta.
This area is called Daguang Valley, which was first mapped in the late 19th century.
This vast expanse, along with the Great Sea, is what makes up the Great Basin.
The water of the river flows through the Great Dome, which connects the Great Ring with the sea.
The valley itself is an immense river, and there are several places where it empties into the sea: in the north, in the Yangtze and the Yangzi, and in the south, in Hubei Province.
The Daguangs are known for their immense waterfalls.
The Yangtzes are huge, and are the source of many of the waterfalls in China.
The Dongzang are also huge, but are also the source for many of China and the worlds biggest springs.
Water is flowing through the great gates, and this water is flowing into the Great Delta.
The river flows to the east, then turns and flows back towards the south in a river called the Yangze.
The great gates are made of mud bricks, which have been carefully placed on top of each other and are made up of sandstone.
The mud bricks are also used for the Great Gates.
They’re made from a mix of limestone, sand and clay, which has been poured into a mortar.
The walls of the walls are made from the same clay and sandstone as the surrounding land.
When the Great Palace of Zhou was built in 1162, the Chinese government commissioned the building of the first Great Wall in China, and then a second wall, the second
