One of the world’s most unique archaeological sites – a band of thousands of holes snaking their way over a mountainside in the Peruvian Andes – has long remained a mystery, with no clear indication of who made it or what it was originally used for.
The site, known in Spanish as Monte Sierpe (Serpent Mountain), first came to broader attention after an aerial photograph of the stone-lined holes was taken in the 1930s and published in National Geographic. At the time, it was hypothesised that the holes were unused pre-Inca civilisation graves.
