Changangkha is a western central district, located between the Chubachu centre and Motithang to the west. It contains the Changangkha Lhakhang. Changangkha Temple is one of the oldest temples in the Thimphu valley, founded by Phajo Drugom Zhigpo, founder of the Drukpa Lineage in Bhutan, and extended by his son Nyima in the 13th century. The temple houses a statue of Thousand-armed Avalokiteśvara as well as very large prayer wheels and unusually large size sacred scriptures. The temple was restored in 1998–99. A well known incense factory, named Nado Poedzokhang,  is located above the Lhakhang in Changangkha.
