How did the Incas cut stone?
The stone blocks are so closely matched that a knife blade cannot be inserted between them, he noted. Previously, scientists have theorized that the massive stones of Incan cities were hammered with other stones, broken with wooden or metal wedges, etched with organic acids or sanded with grains of sand and water.
Construction Process
Some were chiseled from the granite bedrock of the mountain ridge. Built without the use of wheels, hundreds of men pushed the heavy rocks up the steep mountain side. Structures at Machu Picchu were built with a technique called “ldquo ashlar.” Stones are cut to fit together without mortar.
Many theories have been proposed. The most well accepted theory about how the Inca dressed the stones is that they used hammer stones to shape the blocks. Larger hammer stones were used to rough the blocks and smaller stones were used to finish and smooth the blocks.
Anti-earthquake inca walls
The ingenuity of Inca stone masonry doesn't stop at fitting a few blocks together just to build their inca walls. Such construction was necessary to prevent destruction in the event of all too regular earthquakes, and the walls were so designed that they would absorb the impact.
Some of their most impressive inventions were roads and bridges, including suspension bridges, which use thick cables to hold up the walkway. Their communication system was called quipu, a system of strings and knots that recorded information.
The perfectionist Inca stonework is remarkable. This is because they laid the stones so precisely that the use of mortar to hold them together was not necessary. In fact, so perfectly the stones fit, that a piece of paper would not fit between them.

Mostly Granite (igneous rock) and at lesser extent Limestone (sedimentary rock). MACHU PICCHU - Machu Picchu is a city located high in the Andes Mountains in modern Peru.
Today, hundreds of thousands of people tramp through Machu Picchu every year, braving crowds and landslides to see the sun set over its towering stone monuments and marvel at the mysterious splendor of one of the world's most famous manmade wonders.
El quero – El Kero was a pottery from the Inca culture, a kind of glass in which it used to drink liquids like the traditional chicha de jora. It was also made of metal or wood, and was used in Andean celebrations and rites.
What did Incas eat?
The Inca diet, for ordinary people, was largely vegetarian as meat - camelid, duck, guinea-pig, and wild game such as deer and the vizcacha rodent - was so valuable as to be reserved only for special occasions. More common was freeze-dried meat (ch'arki), which was a popular food when travelling.
138. The Incas were superb stonemasons, long before machine tools were invented. They did not use cement, but shaped their blocks of stone so precisely that they fitted together perfectly, so tightly that it is impossible even today to slip even a knife between most of the stones.

The most common type of Inca house was rectangular with a thatched roof, and usually had just one room. The walls were usually made from stone or adobe (a claylike material). The stone blocks were carved so that they fitted together perfectly, and there was no need for cement.
Witness of great events of history, the Inca civilization had three types of architecture: civil architecture (the 12-Angled Stone), military architecture (Sacsayhuaman), and religious architecture (Koricancha). The Inca buildings were erected in rectangular spaces, using materials such as rocks and mudbricks.
Machu Picchu is a protected area and a World Heritage Site since 1983. No one can live inside the citadel. However, during your visit, you will see several llamas, they are not native to the area, but they were bought to Machu Picchu to enhance the site's beauty and trim the grass.
"Most of them still living in the towns of San Sebastian and San Jeronimo, Cusco, Peru, at present, are probably the most homogeneous group of Inca lineage," says Elward.
With their royalty and focus of worship destroyed, the general population readily accepted Spanish rule as “what was done.” This created local assistance which, along with outside factors, allowed the Spanish to completely conquer the region by 1572, marking the end of the Inca Empire.
Most population estimates are in the range of 6 to 14 million.
They could extend the land available for cultivation and provide better water and drainage for crops but they were also sometimes merely decorative and planted with flowers. Those terraces at Pisac and Ollantaytambo are amongst the most impressive and their design has a definite and planned aesthetic effect.
What was impressive about Inca masonry? It was a perfect fit between two large stone blocks. 2b. Were Inca oral traditions successful in preserving information?
What is known about the stone work for the walls in Machu Picchu?
These remain impeccable and showcase the unbelievable skill of the Inca masons. The technique of fitting stones without mortar is known as Ashlar. The Inca refrained from using mortar because the loose-fitting was more resistant to earthquakes and the whole Urubamba Valley was prone to experiencing them.
The men wore simple tunics reaching to just above the knees. On their feet they would wear grass shoes or leather sandals. The women dressed in ankle-length skirts and usually with a braided waistband. They wore a cap on their head and on their hair they pinned a folded piece of cloth.
Contents. Despite the towering reputation of Egypt's Great Pyramids at Giza, the Americas actually contain more pyramid structures than the rest of the planet combined. Civilizations like the Olmec, Maya, Aztec and Inca all built pyramids to house their deities, as well as to bury their kings.
"People were thinking that it dated back to 1450," Richard Burger, a professor of anthropology at Yale University, tells Morning Edition. Burger and his team found evidence that Machu Picchu can date all the way back to 1420, 30 years older than thought.
For decades, the ancient Incan ruins in Peru have been called Machu Picchu. But the original name was Picchu or Huayna Picchu, according to two researchers.
