an important stupa next to the Khorlo-Chu(Kholongchu) River in Trashi Yangtse, in East Bhutan. The stupa was built in 1740 by Lama Ngawang Lodrö (3rd abbot of Rigsum Goenpa), the nephew of Zhabdrung Ngawang Namgyal in memory of his late uncle Lam Jangchub Gyeltshen and to subdue a harmful demon believed to have been living at the site where the stupa is now located. The stupa is modeled after the famous Boudhanath stupa in Nepal popularly known as Jarung Khashor.

here is an annual Dakpa Kora (circumambulation of the Chorten by the Dakpas) festival held on the 15th of the first lunar month, and a Drukpa Kora (circumambulation of the Chorten by the Bhutanese) festival held at the end of the first lunar month which celebrate the stupa. These festivals are attended by Dakpa people of the neighboring Tawang District of Arunachal Pradesh in India, and Bhutanese from Trashi Yangtse, Trashigang, and Kurtoe.
