This article analyzes the Memorial Hall for Victims of the Nanjing Massacre by Japanese Invaders, opened in its present form in 2007 to commemorate the massacre perpetrated by the Japanese in 1937, when in the course of six weeks a significant number of harmless civilians were brutally slaughtered. The memorial is a highly complex semiotic object: it includes a large museum but is also, and perhaps above all, a huge thematic park that occupies an extremely large surface area of seventy-four thousand square meters. Through a close reading of the site, this article seeks to show how the Nanjing Memorial, more than serving the function of conservation and transmission of a tragic, traumatic memory, is mostly a monument to Chinese nationhood, an important step in the construction of a new national identity.
