Dhangkar fortress served as the traditional home of the royal family of Spiti - the Nonos - for many generations before falling into disrepair in the late 1800's, when the Nono shifted his headquarters to Kyuling. In recent years, due to the deterioration of the building, some sections of the gompa have been abandoned and a new gompa has been built further down. Meanwhile, the fort of Dhangkar, destroyed by an earthquake in 1975, now lies in ruins, but is still a place worthy of a visit. From the remnants of the fort one can see vast expanses of the Spiti valley.
Dhangkar is also of art historical importance. Founded between 7th and the 9th centuries, the old temple complex occupies the southern part of the steep mountain slope of the village. The monastery consists of a number of multi-storeyed buildings perched together, giving a fortress like impression. There are five different halls including Kanjur, Lhakhang, and Dukhang where a life size silver statue of Vajradhara, the Diamond Being, is placed in a glass altar embellished with scarves and flowers. Most interesting is the small chapel on the uppermost peak above the main monastery - Lakhang Gongma. The building is decorated with depictions of the Sakyamuni, Tsongkhapa and Lama Chodrag on the central wall
