The Leshan Giant Buddha, located near the city of Leshan in Sichuan Province, China, is a 233-foot (71-meter) tall stone statue built during the Tang Dynasty. It is carved out of a cliff face facing Mount Emei, lying at the confluence of three rivers that flow below his feet. It is the largest stone Buddha in the world and by far the tallest pre-modern statue in the world.
Construction was started in 713 under the leadership of Chinese monk named Haitong, who hoped that Buddha would calm the turbulent waters that plagued the shipping vessels traveling down the river. As it so happens, the mountain range in which the Leshan Giant Buddha is located was thought to be shaped like a slumbering Buddha when seen from the river, with the Leshan Giant Buddha now being at its heart.
However, the project stalled due to insufficient funding and the eventual death of Haitong. About 70 years later, an unnamed jiedushi (regional military commander) decided to sponsor the project, and construction was completed by Haitong’s disciples in 803.
As it turns out, constructing the massive statue resulted in so much stone being removed and deposited into the river below, that the currents were indeed altered by the statue, making the water safe for passing ships as Haitong intended.
In addition to being a marvel of design, the Leshan Giant Buddha is an impressive engineering feat, featuring a sophisticated drainage system carved into various places on the body to carry away rainwater and reduce weathering (hence why it is one of the few stone statues built in a wet environment to remain in fairly good condition). This ancient systems works to this day, although today the Buddha and its surrounding area is threatened by pollution more than anything (the government has promised to restore it).
The Leshan Giant Buddha, along with the Mount Emei area, was listed as a UNESCO World Heritage Site in 1996.
