Yungbulakang was the palace for the first Tubo King Niechi. It is also called "the Mosher and Song Holy Hall." It stands atop a hill on the east bank of the Yalong River in the southeastern part of Naidong County. The castle can be divided into two parts--front and back. The front part is a three-story building, while the back part stands taller, much like a castle. Enshrined here are the statues of Thiesung Sangjie Buddha, King Niechi, King Songtsen Gampo, and other Tobu Kings who reigned after them. There is a legend about a mysterious object on the roof of the castle; therefore, Buddhists regard this place as holy land.
