In the mid 1950s, Thinley Norbu left Tibet at the onset of the Chinese invasion of Tibet. Having fled his homeland, he spent some time in Bhutan, where his children were born. There he served as the chief architect of the Thimphu Memorial Chorten, built in 1974 under the guidance of his father, to honor the memory of the Third King of Bhutan, Jigme Dorji Wangchuck (1928–72).
