Black and white photograph showing a group of people caught in a dust storm. Two people carrying a load between them on a shoulder pole can be seen in the centre of the image, along with other people and rickshaws. A small shed-like structure can be seen behind them, as well as trees and the southeast corner watchtower. The watchtower is part of the city walls that once defined the city of Peking. In their present form the walls date from the Ming Dynasty (1421-1439), but their history can be traced back to the 1200s. The walled city comprised the Tartar or Inner City which lies to the north and the Chinese or Outer City, which adjoins on the south. The walls were pierced by sixteen gates, nine in the Tartar City and seven in the Chinese City. At the hear of the Tartar City lies the Forbidden City, containing the imperial palace with it's own high brick wall coloured red.
