Polish archaeologist Estanislava de Chavez takes notes in the Cundisa archaeological site zone in downtown Copacabana, on the shores of lake Titicaca near the border with Peru, July 4, 2008. Peruvian archaeologist Sergio Chavez says that some of the artefacts found at the site belong to the Tiwanaku and Incan cultures which populated the area thousands of years ago. His team has unearthed several tombs with human remains, as well as textiles, clay pots and jewellery at the site in tourist hotspot Copacabana, which was discovered by chance last month when builders started laying the foundations for a new market.
