The Yuntai (Cloud Platform), located in the center of the pass, is actually the white marble foundation of three white pagodas. Unfortunately, the pagodas were ruined at the end of the Yuan Dynasty (1271-1368), leaving only the rectangular foundation intact.
This foundation is 9.5 meters high (31.2 feet) and has a south -to-north arch. Well-known stone carvings are on the walls and the roof of this arch. The roof is covered with the patterns of stramonium and five Buddha figures. On the walls, ten lifelike, large figures of Buddha are surrounded by many small one s as well as patterns of flowers. Four Heavenly Kings (four gods in Chinese legend who guard the country in four directions) are also engraved here.
Among them, words praising the construction of the pagodas and the Mantras of the Dharani Sutra are carved out in six languages, two of which are Sanskrit and Tibetan. Owing to its historical value and elegant crafting, the Yuntai was included on the list of World Cultural Heritage in 1987.
Peach blossoms in spring, and maple leaves in autumn, make the Juyongguan Great Wall more enchanting. A visit to this area gives visitors a perspective, different from other sections of the Great Wall.
