Đống Đa Mound
Đống Đa Mound () or Đống Đa Hill is a historic tumulus-like mound in the Đống Đa Park (Công viên Đống Đa), in the Đống Đa District, Hanoi, Vietnam. Background Đống Đa Mound is said to be the place where the Battle of Ngọc Hồi-Đống Đa between Tây-Sơn and the Manchu Qing army ended. Having lost, Sầm Nghi Đống () fled and refused to fall into the hands of the Tây-Sơn by hanging himself on Ốc (Loa Sơn) hill. After the war, in order to promote diplomatic relations with the Qing, Sầm Nghi Đống was returned for a state burial and resident Han Chinese were allowed to build a temple on today's Đào Duy Từ street. After the battle, King Quang Trung ordered the bodies of the enemies to be collected and put into 12 large burial mounds. These 12 hills were spread from Thịnh Quang to Nam Đồng villages. As they became overgrown with banyan trees the landscape came to be called Đống Đa, literally Heap of Banyan trees. In 1851, during construction and clearance work for new roads and the Nam Đồng markets, more remains were found and gathered into a big burial next to Ốc hill. This
