Last week, Dennis was at Machu Picchu, near Cuzco in Peru. Machu Picchu ('Old Moutain' in Inca) was constructed by the Inca around 1400. It is not really sure what the site was used for. Some say it was an estate for an Inca emperor, others believe it was built for military purposes. The site was abandoned for centuries before being brought back to international attention in 1911.
