A British-led team has found a lost city of the Incas using hi-tech infra-red cameras.
Llactapata is just two miles from the famous Incan city of Machu Pichu, Peru, which 500,000 tourist visit each year.
Bristol-based explorer Hugh Thomson, 43, made the new discovery 9,00ft up the Andes mountain.
He said infra-red equipment made his task a lot easier. He said: "You can simply see the ruins through the camera."
Thomson thinks Llactapata was an important ceremonial site. It was abandoned about 500 years ago when Incas fled the Spanish Conquistadors.
