A renovated mural depicting the Four Heavenly Kings opposite a prayer hall (2009). The same mural is seen in a ruined stage in the 2004 photo (below, in Structures) at the top of the stairs.

The Diskit monastery was founded by Changzem Tserab Zangpo in the 14th century.[1] Ladakh was then ruled by King Grags-pa-'bum-lde (1400–1440) and his brother, who unsuccessfully attempted to usurp Nubra Valley, which was under a local ruler named Nyig-ma-grags-pa. The local ruler assisted a Gelugpa order advocate to build the monastery at Diskit and deify the idol of Tsong Khapa, the founder of the Gelugpa sect, in the monastery. During the rule of King Blogros-chog-idan (1440–1470) who had even controlled western Tibet, Panchen Lha-btsun - a resident of Nubra Valley by birth - studied in Tibet and later became a regent to the founder of Tashilhunpo Monastery and finally during his last stage of life returned to Nubra. His remains have been preserved in Charasa. In 1500, Ladakh was ruled by Bkra-shis-rnam-rgyal, who fought the invader Mirza Haider of Central Asia, in Nubra and close to Leh, finally defeated the latter and thus brought Nubra under the Ladakh king's rule. Even then, the local chieftains still yielded power in Diskit and India. Shia Muslims started settling in Nubra after this war. Bkra-shis-rnam-rgyal' son, Tshedbang-rnam-rgyal, ruled Ladakh from 1530 and expanded his kingdom. At that time, Nubra people prevailed on him and prevented him from invading Hor in Xinjiang, as trade with Yarkand was considered crucial to Nubra. During the reign of Jams-dbang-rnam-rgyal, historical records indicate that a regular tribute payment was made by the Nubra people to the king. King Bde-'Idanrnam-rgyal (1620–45) successfully defeated Baltistan and the Mughals. Rgyal kings were very religious and built mani walls throughout their kingdom. Monks were specially engaged to recite hymns of Mani-tung chur in Nubra Valley and in other surrounding areas. In the mid-eighteenth century, Tshe-dbang-rnam-rgyal gave control of Diskit monastery to the Rinpoche of Thikse Monastery and this arrangement has been perpetuated to this day. Since then, Diskit is considered a sub-gompa of Thikse.[2]
