颐和园
With the Qing army devastated, the Xianfeng Emperor fled the capital and left behind his brother, Prince Gong, to take charge of peace negotiations. Xianfeng first fled to the Chengde Summer Palace and then to Rehe Province. Anglo-French troops in Beijing began looting the Summer Palace (Yiheyuan) and Old Summer Palace (Yuanmingyuan) immediately (as they were full of valuable artwork).
