The geography of Machu Picchu makes it even more exciting (if that's even possible) , and the landmarks make it 4 times better. The former Inca city lies some 2,000 feet above the Urubamba River that borders 3 of the city's sides, high up on the slopes of the Andes Mountains surrounded by a tropical rainforest. Another thing that's interesting about Machu Picchu is that both its geography and landmarks line up almost perfectly with astronomical events such as the Fall Equinox. Machu Picchu is made up of temples, palaces, plazas, and homes that are still firmly in place , along with walls, terraces, and ramps that blend in with the mountains. Another thing that stands out is the 700+ foot terraces built throughout the city that: promote agriculture, preserve soil, and served as a water distribution center. The most fascinating part of Machu Picchu is that the stones for building were cut to fit perfectly together, without cement or tools, and that it has lasted preserved for hundreds of years. All together, tourist's fascination of Machu Picchu is increased by the geography and landmarks.
