A French expedition has found geoglyphs similar to the Nazca lines in Manu National Park, more precisely in the Pushuro zone. This discovery would confirm the existence of Paititi, the Lost City of the Incas, a mythical sacred city, the archeological enigma of South America.

Paititi refers to the legendary lost city said to lie East of the Andes, hidden somewhere within the remote rain forests of southeast Peru, northern Bolivia, and southwest Brazil. In Peru the Paititi legend revolves around the story of the culture-hero Inkarri, who, after he founded Q’ero and Cuzco, retreated toward the jungles of Pantiacolla, to live out the rest of his days at his refuge city of Paititi. Other variants of the legend see Paititi as an Incan refuge in the border area between Bolivia and Brazil.

Archaeologist and French explorer, "Peruvian of heart", Thierry Jamin is awarded a diploma in History and Geography and in Archaeology at the French Universities of Tours and Toulouse. Since 1998, he dedicates his searches, in the national park of Manú, Madre de Dios, to the study of the permanent presence of the Incas in Amazonian forest. Since several years, an enigmatic archeological site, lost in the Peruvian Amazonian jungle, is the center of all his attention. It is about curious petroglyphs indicated for the first time in 1921 by the Dominican missionary Vicente de Cenitagoya. They have no equivalent in Peru.
Since 2001, Thierry Jamin dedicates an important part of his searches to the study and to the interpretation of the petroglyphs of Pusharo. He revealed the exceptional discoveries realized by his team during his last campaigns: new petroglyphs, the first ones Amazonian geoglyphs never indicated until then, and maybe the rests of an ancient writing. For Thierry Jamin, Pusharo could constitute the "stone of Rosette" of the Inca civilization...
This "geographical memory map", achieved by the Incas toward the end of the 15th century, would indicate, according to him, the site of numerous archaeological sites, distribute on the set of the former territory of the Tahuantinsuyu. Pusharo would then be a very precise map representing the Inca Empire at the time of the administration of Tupac Inca Yupanqui.
