The imperial summer palace, or Yuanming Yuan, evolved over time into the main residence of the Qing emperors. Eight miles north of the Forbidden City, it was constructed throughout the 1700s and early 1800s, as emperors successively added gardens, water features, follies, and eventually European-style palaces.
Yuanming Yuan was burned from October 18th to October 21s of 1860, during the Opium Wars, by the Anglo-British Expeditionary Force. These photographs were taken on October 18th before the palace was burned.
