The Palacio de Lecumberri is a large building, formerly a prison, in the northeast of Mexico City, Mexico, which now houses the General National Archive (Archivo General de la Nación). Known in popular culture as The Black Palace of Lecumberri, it served as a penitentiary from 1900 to 1976. It was inaugurated by President Porfirio Díaz. The building was decommissioned as a prison in 1976 and turned over to the country's National Archive in 1980.
