Machu Picchu, Peru...
The ancient city of Machu Picchu was build lived in and deserted
in fewer than 100 years then lost to civilization for centuries. During
construction, the Inca didn`t use wheels to transport the blocks, instead they
hauled them up the slopes by hand as protrusions have been found on a few
stones. Ingenious engineering solutions were used to counteract earthquakes.
