The Fortress of Machu Picchu

Machipicchu is a self contained mountain fortress. There were terraced fields, running water, storage buildings, housing, temples, observatories for sun and stars, and watch towers. The city was never invaded by the Spaniards, but suddenly abandoned by the Incas for reasons not fully known. The ruins were discovered in July of 1911 and many artifacts were removed from the site. It has also been estimated that the site will be closed to visitors in 10 years to preserve the site from human touch. 

When I catch that Spaniard that took my hat, it's on.

What a beautiful place for a city.
