Machu Picchu is a significant Inca archaeological site in the Peruvian Andes, recognized as a UNESCO World Heritage site. The complex is known for its advanced dry-stone masonry, temples, residential areas, and agricultural terraces.

Recent archaeological efforts by a Polish-Peruvian team have led to the discovery of over 2.5 kilometers of previously unknown Inca roads, as well as terraces, platforms, and circular structures on the slopes of Yanantin Mountain. These findings were located beneath dense tropical rainforest and were identified using LiDAR technology via drone scanning to penetrate the canopy. The discovery suggests that the historical sanctuary still contains significant undiscovered elements.
