For Peru and even for the whole of South America, our visit to the Inca city of Machu Picchu was the long-anticipated highpoint of our trip. It is a truly spectacular location and understandably the best-known archaeological site on the continent and a Wonder of the World. This awe-inspiring ancient city was never revealed to the conquering Spaniards and was virtually forgotten until the early part of the 20th century when it was rediscovered by Hiram Bingham III in 1911. It is renowned for its sophisticated dry-stone walls that fuse huge blocks without the use of mortar, intriguing buildings that play on astronomical alignments and panoramic views. Its exact former use remains a mystery, albeit Bailey dubbed it Llama City.
