Formerly called No. 4 Park, the name of this expanse of green changed to 823 Memorial Park after a monument was erected in it to commemorate victory in the Second Taiwan Strait Crisis, which had begun with the 823 Artillery Bombardment. The park is located at the Zhonghe-Yonghe border and at 10 hectares is the largest park in either district. The National Taiwan Library is here, as is a spacious green area and forest path, plus basketball courts and playgrounds. Local residents come to exercise, whether it is walking or taking their dog for a stroll, and to enjoy a rare expanse of green in this dense urban zone.
