The use of ashlar masonry allowed the Incas to create resilient architecture suited to their mountainous landscape.
Explanation:
Inca Architecture at Machu Picchu
The architectural technique employed by the Incas at Machu Picchu is known as ashlar masonry. This method is characterized by fitting large stones together tightly without the use of mortar, creating structures that are remarkably durable and stable. The skill of Inca masons in shaping stones allowed for the construction of monumental structures that have stood the test of time.
Inca architecture is widely recognized for its fine masonry, featuring precisely cut and shaped stones closely fitted together. Although many Inca buildings incorporated fieldstones or adobe, it is the use of ashlar masonry that highlights the engineering prowess of the civilization. Notable examples of this technique can be seen at Machu Picchu and other sites like Sacsayhuamán, where the intricate stonework has survived for centuries.
The effectiveness of ashlar masonry lies in its interlocking stones that rely on gravity and friction to stay in place, resulting in structures that are resistant to earthquakes, a significant consideration in the Andes region. This method not only demonstrated the Incas' mastery of stone but also their adaptation to the rugged terrain of their environment.
