Langna is a Sakya monastery in Kandze, Kham. It is said to have been founded in the early eighteenth century by the Tenth Chogye Trichen of Nalendra Monastery, Khyentse Rabten who passed through Kandze on his way to China. It takes its name from the ridge on which it sits, which is said to resemble an elephant's trunk. Some sources assert that it was first established by Pakpa Lodro Gyeltsen in 1276.
