Dakpa Kora is held on the 15th day of the 3rd month corresponding to 28th February and Drukpa Kora (circumbulation by the Bhutanese) is held on the 30th day corresponding to 15th March every year (Check with your tour operator to confirm these dates).
The Chorten (Stupa) was built by Lama Ngawang Loday in 1740on the site where a demon was subdued. The chorten was dedicated to the memory of his late uncle, Jungshu Pesan. It is believed to be a replica of the Boudhnath stupa in Nepal and was consecrated by the 13th chief Abbot of Bhutan Je Sherub Wangchuk. Today, it is considered one of the most important historical Buddhist structures.
It chorten was built so that pilgrims could visit the temple in Trashiyangtse instead of making a trip to Nepal. Further, a legend states that a young girl from Tawang, believed to have been a Khando (Dakini) agreed to be buried alive inside the Chorten. For this reason a ritual known as Dakpa Kora is organized every year where hundreds of people from Arunachal Pradesh known as the Dakpas make it to Chorten Kora to circumambulate.
