Match the heading to the short text. It was 24th July 1911. Hiram Bingham, an American archaeologist, was in the Andes mountains in Peru. Suddenly he saw walls of stone in front of him. He couldn't believe it! Was this the lost city of Machu Picchu? Machu Picchu is an ancient Inca site in the Andes Mountains in Peru. It dates back to 1436. But what was it exactly and why did the Incas build it so high in the mountains? No one is really certain.
