Trashigang Dzong built in 1659, is one of the Dzongs prophesized by Zhabdrung Ngawang Namgyel, the founder of Bhutan and played instrumental role in the unification of eastern Bhutan. It also defended external invasion from Tibet. Presently the Dzong is used as the seat for Rabdey and Administration of Trashigang Dzongkhag
Trashigang Dzong suffered structural damages in the eastern and northern side after the earthquake of September 2009. Minor repair works have been executed on the site after the earthquake, which has not been able to consolidate the major damaged parts. Major consolidation to the structure was found necessary and therefore the conservation project was started in the beginning of 11th FYP.
