The memorial (place to remember something) consists of three major parts: a museum that shows historical records and other things from the massacre, an outdoor area, and a covered area that holds the bones of many of the people who died in the massacre. The building has about 3,000 square meters or 32,000 square feet of floor space. The rest of the museum covers another 25,000 square meters or 6 acres of land around the building. The memorial uses architecture, sculptures, and videos to show what happened during the Nanjing Massacre.
