For all of the study that's been done in the "Lost City" of Machu Picchu — not to mention all of the travelers who have waked the ruins of the ancient citadel — archaeologists are still finding clues about the lives of the Inca who lived here.

A group of Peruvian archaeologists from the National Institute of Culture discovered ceremonial offerings buried under Machu Picchu, including three ceramics or miniature aryballos with globular body and covered with stone slabs forming a circle, known as "apachetas."

"These are likely to be part of a ceremonial rite of payment to the land, the only of its kind found in Machu Picchu," said archaeologist Ruben Maqque.

He also said that the findings took place at a sector known as Cementerio ("Cemetery"),where there are nine different types of rocks, brought from several parts of Cusco by the Inca workers. There were no traces of skeletal remains, which rules out the hypothesis that the place was an Inca cemetery. However, archaeologists believe that this was an exclusive site for ceremonial rites.
