Chorten Kora, located in Trashiyangtse observes its festival for two days held on the 15th day of the 3rd month corresponding to 28th Feburary (Dakpa Kora) and on the 30th day corresponding to 15th March (Drukpa Kora). The Chorten (Stupa) is one of the most important historical Buddhist structures built by Lama Ngawang Loday in 1740 in memory of his late uncle, Jungshu Pesan and also to subdue a demon that lived where the Chorten now stands.
A ritual known as Dakpa Kora is organized every year as a legend states that a young girl from Tawang, believed to have been a Khando (Dakini) agreed to be buried alive inside the Chorten. People from Arunachal Pradesh known as the Dakpas make it to Chorten Kora to circumambulate on Dakpa Kora. And for Drukpa Kora, the Bhutanese people make circumbulation of the Chorten.
