We left Thimphu early in the morning heading over the 3,050-meter mountain pass of Dochula towards Punakha. There are 108 memorial chortens here known as “Druk Wangyai Chortens” built by Ashi Dorji Wangmo Wangchuk, the eldest Queen Mother. They were built in memory of the soldiers who died in the December 2003 battle against the Assamese insurgents from India. Chortens are stupas important to Tibetan Buddhism and are usually tombs of saints or distinguished lamas or monuments to the Buddha. The chortens at Dochula Pass are built in 3 layers with 45 chortens in the lowest level, 36 in the second layer, and 27 in top layer surrounding the main chorten. Nearby is the Druk Wangyal Lhakhang built to celebrate 100 years of monarchy in Bhutan.
