The Great Wall of China, the most extended architectural structure ever constructed, is a series of short walls made of several materials like brick, stone, tamped earth, and wood. The wall located in Beijing, China, was originally built between the 7th and 8th century BC as a fortification to protect the Chinese Empire’s borders from enemies and northern invaders, especially the Mongolians. Like a giant dragon, the Great Wall winds up and down across the crests of mountains, grasslands, deserts, rivers, and forest, spanning across 21,196km from east to west of China. Its rugged landscape provides beautiful scenery for tourists all year round. It would take approximately 18 months to walk the wall’s length. The Great Wall of China is one of the Seven New Wonders Of The World and was listed as a World Heritage site in 1987 by UNESCO.
