Shadzong Ritro, a Geluk hermitage located in the Tsongkha region of Amdo and situated on a slope of Amnye Chi Ri, is one of four major meditation sites in Amdo. It was founded in the twelfth century. Legend states that Faxian (337-422) stayed at the location while traveling to India. The Fourth Karmapa stayed at the site and is said to have prophesied the birth of Tsongkhapa, who took his novice vows here at the age of three. The hermitage was expanded over time and in 1383, a temple hall and stupa were built to commemorate the Fourth Karmapa. The site was partially destroyed during the cultural revolution. As of 1999, there were four monks at the hermitage. At some point, relics of Fa Xian were located at Shadzong.
