Badaling Great Wall is the most famous section of the Great Wall and is the best preserved part of the Ming Great Wall. It averages 7.8 meters high, 6.5 meters wide of the base, and 5.8 meters at the top. The wall was designed to allow five horsemen or ten soldiers to march side by side along the wall. The flights of stairs up to the outer wall are fairly widely spaced.

 

The wall could almost be considered as a superhighway on the rough mountain terrain. On the highway, news, men or even food could travel rapidly. Suppose you were a solider 500 years ago in the Ming Dynasty, when you found some enemies were about to invade your country, in the daytime, they should start a heavy smoke to tell the other soldiers to get ready, when seeing their signal, would start another smoke in the distance, this signal would be relayed until finally it reached the capital and the whole country would be ready for the war. But what if the enemies invade the country at night, as most invasions started, they should light up beacon-fires to communicate military information to the emperor at a very rapid speed.

 

For every few hundred meters, you can see a watchtower. Also, the wall of this section was built of giant rocks and bricks of similar size. It was faced with stone, and the inside was filled with earth and rubber, therefore, Badaling Great Wall was also regarded the strongest section of the Ming Great Wall.

 

To experience the real splendor of the Great Wall, you should not only see the Great Wall and take pictures from down here, but also walk on it. There're two entrances where you can climb the Badaling Great Wall, most people, however, climb the Great Wall from the right entrance because it is an easier way. It takes about an hour to climb to the top of the raised towers either way. From the top on the right looking northwest, you can see the famous Guanting Reservoir. The wall on the left is a little steeper, naturally, less people climb the wall from this side.
