Building works started on the Great Wall during the Qin dynasty more than 2,000 years ago. This fantastic monument is about 5,000 miles long. Its height varies from 15 to 30 feet, with a breadth of up to 30 feet as well. The wall has a number of watchtowers and ancient fortifications for stationing the ancient armies tasked with preventing incursions by neighboring tribes. The "Spaced Out" program on the Science Channel confirms the belief that parts of the wall can be viewed from outer space, indicative of the massive nature of this manmade monument.
