In a sand-dusted cemetery in the desert, 30 kilometers south of the city of Nazca in Peru, lie the skeletal remains of an ancient people. Inside the open tombs there are not simply scattered bones but whole human mummies, as well as archeological artifacts. Skulls leer up at those souls who venture down the dirt track that leads to this sepulchral site; skeletons in virtually the same ghastly poses in which they were frozen a millennium and more ago. If you ever wanted to see what you might look like after death, these figures – complete with hair – offer a glimpse. Do ghosts haunt this creepy South American burial ground? We wouldn’t be surprised.
