| | We visited the Simatai section of the great wall. | |
| | | This section is one of the roughest and steepest of the entire wall. | |
|
| | The wall was started in in 200 BC and took 100 years to complete. | |
| | | The first wall was just made from packed earth and was started by Qin. | |
|
| | Later emperors completed the wall with brick- 60 million cubic meters of it. | |
| | | The wall strecthes more than 3600 miles...longer than the US is wide. | |
|
| | It was built to help protect the Chinese from the Mongol hordes from the north. | |
| | | It also served as an elevated highway- horses could travel two abreast. | |
|
| | Smoke signals could be set up from the towers by guards stationed at each. | |
