This view of the ruins of Donkar-jong castle on a hillside is from a collection of 50 photographs of central Tibet acquired in 1904 from the Imperial Russian Geographical Society in Saint Petersburg by the American Geographical Society. According to the photographer’s notes, Donkar is a village on the route from Lhasa to Tashi-lhumpo (also seen as Tashi-lhunpo in other sources), about five miles (eight kilometers) to the west of Lhasa. The photographs in this collection were taken by two Mongolian Buddhist lamas, G.Ts. Tsybikov and Ovshe (O.M.) Norzunov, who visited Tibet in 1900 and 1901. Accompanying the photos is a set of notes written in Russian for the Imperial Russian Geographical Society by Tsybikov, Norzunov, and other Mongolians familiar with central Tibet. Alexander Grigoriev, corresponding member of the American Geographical Society, translated the notes from Russian into English in April 1904.
