List of walls - Wikipedia

The Great Wall of China is the longest in the world and has a main-line length of 3,460 km (2,150 miles - nearly three times the length of Britain - plus 3,530 km (2,193 miles) of branches and spurs. Construction of the wall began during the reign of Qin Shi Huangdi (sometimes spelled Qin Shihuangdi or Qin Shi Huangdi, 221-210BC). Its height varies from 4.5 to 12 m (15 to 39 ft ) and it is up to 9.8 m (32 ft ) thick. It runs from Shanhaiguan, on the Gulf of Bohai, to Yumenguan and Yangguan and was kept in repair up to the 16th century. Some 51.5 km (32 miles)of the wall have been destroyed since 1966, and part of the wall was blown up to make way for a dam in July 1979.

The history behind the largest dog breeds often reveals dogs bred to be ancient guardians, fierce hunting hounds or royal companions.

While some owners in recent years prefer smaller dog breeds for city living , size and strength have historically been desirable factors to breed into dogs, making them better protectors and hunters.

Although imposing, the biggest dog breeds also tend to be mildly tempered and make excellent family pets. This list details some of the biggest of the big dogs, but “big” is relative; some breeds are stout and heavy while others are tall and lean.

See List of fortifications for a list of notable fortified structures. For city walls in particular, see List of cities with defensive walls (regional list: List of town walls in England and Wales ).

If the Seven Wonders of the World demonstrate the human race's most impressive creations, then the Seven Wonders of the Natural World are proof — if proof is needed — that Mother Nature is just as talented an architect.

The Seven Natural Wonders of the World are the Grand Canyon in the United States, the Paricutin volcano in Mexico, the Northern Lights, the harbor of Rio de Janeiro in Brazil, Victoria Falls in Zambia/Zimbabwe, the Great Barrier Reef in Australia and Mount Everest in Nepal.

Compiled by CNN and Seven Natural Wonders in 1997, this list spans all 7 continents, and includes some of the greatest heights of the earth and depths of the oceans, some lesser known sites, and some well-known features that you may have already visited yourself.

While the list of Natural Wonders is often disputed, these seven locations are generally agreed upon as being among the most breathtaking natural sights anywhere in the world.
