Construction was started in AD 713, led by a Chinese monk named Haitong. He hoped that the Buddha would calm the turbulent waters that plagued the shipping vessels travelling down the river. When funding for the project was threatened, he is said to have gouged out his own eyes to show his piety and sincerity. Construction was completed by his disciples ninety years later. Apparently the massive construction resulted in so much stone being removed from the cliff face and deposited into the river below that the currents were indeed altered by the statue, making the waters safe for passing ships.

The Giant Buddha is located East of Leshan City in Sichuan Province near the confluence of the Min River and Dadu River.

At 71 metres (233 feet) tall, the statue depicts a seated Maitreya Buddha with his hands resting on his knees. His shoulders are twenty-eight metres wide and his smallest toenail is large enough to easily accommodate a seated person. There is a local saying: "The mountain is a Buddha and the Buddha is a mountain". This is partially because the mountain range in which the Leshan Giant Buddha is located is thought to be shaped like a slumbering Buddha when seen from the river, with the Leshan Giant Buddha as its heart.
