The Jakar Dzong or the “Castle of the White Bird” dominates the Chamkhar valley and overlooks the town. Constructed in 1549, by the Tibetan Lam Nagi Wangchuk, the Dzong played an important role as the fortress of defense of the whole eastern Dzongkhags. It also became the seat of the first king of Bhutan. A special feature of the Dzong is the approximately fifty meter high Utse or the Central tower, which is distinct from most other Dzong’s in Bhutan.
The other unique feature of the Dzong is a sheltered passage, with two parallel walls, interconnected by fortified towers, which gave the population of the fortress access to water in the case of a siege. The protected water supply is still intact to this day. Jambey Lhakhang: This monastery was built in the 7th century by the Tibetan king, Songtsen Gampo. It is one of 108 monasteries which he built to subdue evil spirits in the Himalayan region. Its present architectural appearance dates from the early 20th century.
