Inca Stonework refers to the impressive masonry techniques used by the Inca Empire, which thrived in South America from the early 15th century until the Spanish conquest in the 16th century. The Incas are known for their ability to fit large stones together without the use of mortar, creating structures that have withstood earthquakes and the test of time. Their precise stone-cutting methods allowed for tight joints, which contributed to the durability of their buildings. Notable examples of Inca Stonework can be found in sites like Machu Picchu and Sacsayhuamán. These structures often feature trapezoidal doorways and windows, which not only enhanced their aesthetic appeal but also provided structural stability. The Incas utilized local materials, primarily granite, and their techniques have influenced modern masonry practices.
