Introduction to the stupa: The stupa, also known as the stone palace, is constructed entirely of sandstone slabs. The plane is square in shape, with each side 8.8 meters long. It is equipped with an arched slate door in the style of a pavilion with double eaves. The eaves of the tower are stacked on three levels, and a square caisson is formed inside. Purlins and rafters are installed on the four slopes above. Dougong supports eaves and ridges. Be prepared, with pointed orbs on top at the four corners. It looks like a pagoda but not a pagoda, and looks like a palace but not a palace. It is the only existing ancient pagoda from the Tang Dynasty in my country.
