Ruins and remains. Archaeologists in Peru have discovered a tomb that was constructed more than 1,000 years ago, before the Inca Empire, at a site known as the Matacón cemetery, near the town of Huaral. They found human remains and ceramic artefacts belonging to the Chancay culture, an ancient civilization that once inhabited the country’s central coast valleys. The tomb might have belonged to a high-ranking figure who was buried along with the bodies of sacrificed servants or relatives, as well as four llamas. Researchers say the site’s proximity to houses could have prevented the tomb from being looted.
