The memorial occupies the site of what was once Torreón's Barrio Chino, the neighbourhood where the city's Chinese community lived and worked before the events of May 1911. During the Mexican Revolution, as revolutionary forces seized the city, an estimated 300 Chinese immigrants were killed in a matter of hours — shot, beaten, and hanged by soldiers and civilians. It was one of the deadliest acts of anti-Chinese violence in the Americas and a largely forgotten chapter of Mexican history until recent decades.
The memorial is a sober place rather than an elaborate monument. It acknowledges a massacre that the Mexican government was slow to confront and that is still not widely taught in schools. Coming here is not comfortable, but that is rather the point. For context on what you are seeing, visit the Museo Regional de La Laguna first, where the events are covered in more depth.
