Tucked away in the Andes, stands the most amazing archaeological structure chosen as one of the New 7 Wonders of the Modern World on July 7, 2007. This is the 15th-century Inca citadel located northwest of Cuzco on a mountain ridge 2,430 metres (7,970 feet) above sea level. This engineering work of art, balances on this ridge laid out in a series of terraces each one above the other. For over 500 years, the stonework supporting the layout stands with no mortar or cement. The ruins of Machu Picchu reveal the mysteries of the Inca Empire. 

Yes evidence of the pressure exerted by the weight of the soil and stone shows that not all were successful. With an average rainfall of 70 inches we can understand why. These terraces built for farming purposes were for the growing of potatoes and corn. Water was needed for growth but it also had to be managed. Too much water and the mountaintop were eroded, too little and the crops failed. Parts of the dwellings are 2 and 3 stories high. It is believed that Machu Picchu was constructed as an estate home for the supreme ruler or emperor Pachacuti 1438 - 1472. He was the single ruler of the Inca Empire. Addressed as Chief Inca, Son of the Sun or Lover of the Poor, thought to have descended from the Sun. Like the Pharaohs of Egypt he took his sister for his Queen in the belief of true royal blood. The small American Indian people built one of the largest tightly controlled empires the world has ever known. Their skill in Government was matched only by their feats of engineering. Walls, roads and irrigation works constructed by these crafts people are still in use today. To appreciate the Incas achievements it helps to visualize the different terrain of Peru. Some of the world's driest deserts, looking upwards as the land rises to the jagged peaks of the Andes mountain range. The Inca Empire had ruled a population of 12 million people.

With the invasion of the Spanish however in the 1500's South America was under serious danger of being overthrown. The Spanish first overcame the Aztec Empire in Mexico. Crossing over to the west they discovered the Pacific Ocean in 1513. Sailing down the coast over a number of expeditions they went as far as present day Colombia, later to Ecuador, then to Peru. Having heard of the wealth in Peru the Spanish governor financed Francisco Pizarro to explore it. In 1533 under the guise of an act of friendship the 13th emperor came to dinner with the Spaniard. The Spanish had an army of 180 trained soldiers. The Inca Emperor was ordered to take the bible and convert to the new religion, he refused and the Spanish army attacked leaving thousands of the unarmed Incas dead. The execution of Atahualpa, the last Inca Emperor, marked the end of 300 years of Inca civilization.

Machu Picchu was never reached by the Spanish conquistadors and lay abandoned to the world until 1911 when an American explorer Hiram Bingham reached there with the help of some local farmers who were struggling to survive generation after generation had seen the end of the glorious Inca Empire.
