This photograph by Alfred Rowden was taken on part of the silk road though Iran. It shows the ancient ruins of a ‘caravanserai’, which was a place for traders to rest whilst on the journey. Rowden calls this site Bisitun but it is more commonly known as Behistun, and is now a World Heritage Site. Rowden was in Mesopotamia during the First World War and was not sent home until 1919 or 1920. He photographed scenes like this to record his experiences.
