Question: why was wangdue dzong built?
Answer: Landmark in Bhutan Zhabdrung Ngawang Namgyel was supposedly at Chimi Lhakhang in Punakha when he met a decrepit old man. He described a ridge in the present-day Wangdue Phodrang as a 'sleeping elephant' and told Zhabdrung that he would unite the country by building a Dzong on the 'neck' of the ridge.
