The Pingyunnan Stele of the Emperor Yuanshizu is in the center of March Street Square in the western part of the ancient City of Dayushi, at the foot of Zhonghe Peak in Cangshan Mountains. The stele was built in 1307, the 11th year of the reign of Yuan Dynasty Emperor Chengzhong. It is 4.44 meters high and 1.65 meters wide. It is made of two huge pieces of granite standing on the back of a stone turtle, hence its other name of Turtle Stele. It records how Yuan Emperor Khublai Khan pacified Yunnan and divided it into counties. Also it explains how Yunnan Province was established.
