The Great Wall is not located in any one given city. Some areas of the Great Wall offer magnificent vistas and picture-perfect brick-and-stone watchtowers, whereas older, pre-Ming areas may be in disrepair yet would certainly impress any archeology aficionado. Very early parts of the Great Wall were constructed from tamped-earth and, where possible, stone. These areas of the Wall are particularly prone to erosion and deterioration.The modern day Great Wall crosses Liaoning, Shanxi, Shaanxi, Sichuan, Jilin, Shandong, Hubei, Hunan, and Gansu provinces; Beijing and Tianjin municipalities; Inner Mongolia and Ningxia Autonomous Regions.
