The Cloud Platform (Yuntai), also called "Crossing Street Tower," is a section of the Great Wall of China built in 1345. It supported three pagodas--the tiered towers with several over-hangings common in China and Japan--but lasted for less than three decades. The Cloud Platform also supported the Great Peace Temple, but in 1702 a fire destroyed it. It now stands alone as a marble archway and platform for people to enjoy scenic views. Its exterior and ceiling house carvings; images of animals, the Buddha and flowers; mandala patterns, and inscriptions of Buddhist scriptures.
Juyong Pass, or Juyongguan, is near Beijing and was built in the 5th century and updated during the Ming Dynasty between 1368 and 1644. National Geographic states that it served as a trading post and military fortification. It rests in a ravine, and its scenic views of green trees and colorful flowers make it popular among visitors. People can still make out the inscriptions and carvings that adorn its walls.
Badaling is the most popular site for tourists, as it is the highest point of the Great Wall of China. It rises over 1,000 meters above sea level, and standing on the watchtowers affords visitors scenic views. While modern features include handrails and vendors for tourists, historically it was built during the Ming Dynasty and served as a military bunker.
Mutianyu, which the Ming Dynasty saw reconstructed, was the site of several battles in Chinese history. It served as a military stronghold when Emperor Yongle made Beijing the capital during his reign in the first quarter of the 15th century. Attacks continued during the reign of child emperor Zhengtong in the second quarter of the 1400s. Mutianyu houses 22 watchtowers and is now popular among tourists, according to National Geographic.
