The elders in the locality vividly remember that the present Trashicho Dzong was proposed to be constructed on the hillock where present day Rangjung Woesel Choeling Monastery is located. They believe that the local spirit at that time obstructed construction of the Dzong and finally diverted to Thimphu dzongkhag. The monastery was founded by His Eminence Dungsey Garab Dorje Rinpoche in the year 1989 and became an iconic place for worshiper of Dudjom New Treasure Lineage. The daily prayers of monks and nuns along with melodious sound of religious instruments keeps small satellite town of Rangjung lively and free of misfortunes.
