The second installment of the article series "The Architecture of Machu Picchu" delves deeper into the intricacies of this ancient Incan city's design and construction. The article begins by highlighting the importance of Machu Picchu's location, situated on a ridge between two mountains in the Andes. This positioning not only provided the city with natural protection but also offered breathtaking views of the surrounding landscape.

The author then proceeds to describe the architectural features of Machu Picchu, focusing on the incorporation of natural elements into the design. The Inca architects skillfully integrated large rocks, which were left in their natural form, into the city's walls and buildings.

This technique not only saved on labor but also created a harmonious union between the man-made structures and the natural environment. Additionally, the use of terraces and agricultural areas demonstrated the Inca's advanced understanding of engineering and agriculture.

The article goes on to discuss the impressive drainage system present at Machu Picchu. Built with stone channels, the system effectively managed water flow and prevented erosion. This demonstrates the Inca's knowledge of hydrology and their ability to create sustainable infrastructure.

Furthermore, the author highlights the architectural precision of Machu Picchu's construction.

The stones used in the city's buildings were cut and fit together with such precision that no mortar was needed to hold them together. This engineering feat not only showcases the Inca's advanced construction skills but also ensured the structures' stability.

In conclusion, the second part of this article emphasizes the skillful incorporation of natural elements, impressive drainage system, and architectural precision that characterize the design and construction of Machu Picchu. These aspects contribute to the city's historical and cultural significance, making it a marvel of ancient Incan architecture.
