With assistance from the National Geographical Society Machu Pichu was discovered for the outside world by American explorer Hiram Bingham in 1911. It is a site the Spanish did not find during their invasion which left it as the largest complete Inca settlement. It is perfectly landscaped and contains royal, ceremonial and religious architecture along with astronomical alignments. It survives as a perfect example of Inca planning and engineering.
