Longmen Grottoes
In the cliffs under Luohan Peak, in the Western Hills, are the Longmen Grottoes, with a stone gate leading to the Datiange chamber. 2,300 metres above sea level, these are the largest Taoist grottoes in Yunnan. It took 72 years to build these grottoes during the Qing dynasty, from the 46th year of the Qianlong Emperor's reign (1782) to the 3rd year of the Xianfeng Emperor's reign (1854). The project was undertaken by stone craftsmen living at the foot of the Western Hills. It is said that the workers could get a measure of rice for each measure of stone, poor payment for such hard and dangerous work.
