A tunnel in the 3000 year old Chavín de Huántar. It is thought that shamans gave nonbelievers hallucinogens and set them loose into the maze of tunnels, scaring them into believing their religion with a combination of artwork and sounds. The Chavin cult ruled much of the coastal and Ancash regions of Peru for about 500 years.
