The Dochu La ( Dochu Pass, la means pass in Dzongkha) is a mountain pass in the snow covered Himalayas within Bhutan on the road from Thimphu to Punakha where 108 memorial chortens or stupas known as "Druk Wangyal Chortens" have been built by Ashi Dorji Wangmo Wangchuk, the eldest Queen Mother. Apart from the chortens there is a monastery called the Druk Wangyal Lhakhang (temple), built in honour of the fourth Druk Gyalpo (head of the state of Bhutan), Jigme Singye Wangchuck; the open grounds in its front yard is a venue for the annual Dochula Druk Wangyel Festival.[3] The pass with 108 memorial chortens is adjacent to the country's first Royal Botanical Park. The Druk Wangyal Khang Zhang Chortens are red-band or khangzang chortens, 108 in numbers, built in a central hillock at the pass, under the patronage of the Queen Ashi Dorji Wangmo Wangchuk. In local language they are called gYul Las rNampar Gyal wai' chortens or chortens of victory. These were built as a memorial in honour of the Bhutanese soldiers who were killed in the December 2003 battle against Assamese insurgents from India. It particularly marks the victory of King Jigme Singye Wangchuck who dislodged the rebels from their camps (there were 30 camps) in Bhutanese territory from where they raiding Indian territory of Assam. After the war the king went back to Thimphu on 28 December 2003 and at this stage the 108 chortens were being built. They were completed in mid June 2004 and formally consecrated and sanctified with religious rites held on 19–20 June.
