Shashur or Sashur Monastery is a Buddhist Monastery of the Drugpa sect in Lahaul and Spiti, Himachal Pradesh, northern India. It is located 37 kilometres from Manali. Sha-shur means "blue pines" in the local dialect, as patches of blue pine can be seen around the Monastery.
This Monastery was built in the 17th century by Lama Deva Gyatsho of Zanskar who was a missionary of Nawang Namgyal, the king of Bhutan. However, a smaller gompa had existed previous to the current building.
This Monastery has large Thangka paintings, some of them over fifteen feet, and wall paintings depicting all the 84 siddhas of Buddhism. In the month of June or July Chham is performed in the Monastery.
