Peru is a country located in South America. It is bordered by Brazil in the east and the Pacific ocean in the west. Peru is an extremely biodiverse country with habitats ranging from the arid plains of the Pacific coastal region to the peaks of the Andes mountains and to the Amazon.
However, this presentation will not be about Peru per say. It is going to be about a place based 2 430 m above sea level. Machu Picchu, the forgotten Inka city, which was virtually wiped out by Spanish conquerors in the 16th century.
According to the National Geographic The Inca civilization flourished in ancient Peru between 1400 and 1533, making it the largest empire ever seen in the Americas and the largest in the world at that time.
The Incas, the indigenous people in America, constructed large buildings, walls and fortifications using finely-worked blocks - either regular or polygonal - which fitted together so precisely no mortar was needed.
The site of Machu Picchu has finely crafted stonework, terraced fields, sloping trapezoid form and sophisticated irrigation system, that blend seamlessly into its natural setting and bear witness to the Inca civilization’s architectural, agricultural and engineering prowess.
Its central buildings are prime examples of a masonry technique mastered by the Incas in which stones were cut to fit together without mortar. Still, to this day, a knife blade can’t fit in between the rocks (boulders). The site stretches over an impressive 5-mile distance, featuring more than 3,000 stone steps that link its many different levels.
