USA HISTORY

Detailed explanation-1: -Inca architecture is widely known for its fine masonry, which features precisely cut and shaped stones closely fitted without mortar ("dry"). However, despite this fame, most Inca buildings were actually made out of fieldstone and adobe as described above.

Detailed explanation-2: -They were known for their stonemasonry which did not use mortar. Most buildings the Inca constructed were rectangular structures. These structures were made from stone but had thatch roofs. These buildings arranged around a central courtyard were known as a kancha.

Detailed explanation-3: -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.

Detailed explanation-4: -The Incas were masters of this technique, called ashlar, in which blocks of stone are cut to fit together tightly without mortar. The Incas were among the best stone masons the world has seen, and many junctions in the central city are so perfect that it is said not even a knife blade fits between the stones.
