Five limestone hills shaped by erosion have each been given the name of one of the five elements – water, earth, fire, metal and wood. Together these are known as the Marble Mountains or Mountains of the Five Elements. According to popular legend, these were formed from fragments of egg shell from which a dragon emerged. Dotted with caves and pagodas, the site is popular with visitors who come here to worship the statues of Buddha or other gods from the Buddhist, Confucian and Taoist religions.
