Machu Picchu stands 2,430 meters above sea level, in the middle of a rain forest, in an extraordinarily beautiful setting. It was probably the most amazing urban creation of the Inca Empire at its height; its giant walls, terraces and ramps seem as if they have been cut naturally in the continuous rock escarpments. The natural setting, on the eastern slopes of the Andes, encompasses the upper Amazon basin with its rich diversity of flora and fauna. Since 2000 Machu Picchu is considered one of the New Seven Wonders of the World. Brief Synthesis Embedded within a dramatic landscape at the meeting point between the Peruvian Andes and the Amazon Basin, the Historic Sanctuary of Machu Picchu is among the greatest artistic, architectural and land use achievements anywhere and the most significant tangible legacy of the Inca civilization. Recognized for outstanding cultural and natural values, the mixed World Heritage property covers 32,592 hectares of mountain slopes, peaks and valleys surrounding its heart, the spectacular archaeological monument of “La Ciudadela” (the Citadel) at more than 2,400 meters above sea level. Built in the fifteenth century Machu Picchu was abandoned when the Inca Empire was conquered by the Spaniards in the sixteenth century. It was not until 1911 that the archaeological complex was made known to the outside world. The approximately 200 structures making up this outstanding religious, ceremonial, astronomical and agricultural centre are set on a steep ridge, crisscrossed by stone terraces. Following a rigorous plan the city is divided into a lower and upper part, separating the farming from residential areas, with a large square between the two. To this day, many of Machu Picchu’s mysteries remain unresolved, including the exact role it may have played in the Incas’ sophisticated understanding of astronomy and domestication of wild plant species. The massive yet refined architecture of Machu Picchu blends exceptionally well with the stunning natural environment, with which it is intricately linked. Numerous subsidiary centres, an extensive road and trail system, irrigation canals and agricultural terraces bear witness to longstanding, often on-going human use. The rugged topography making some areas difficult to access has resulted in a mosaic of used areas and diverse natural habitats. The Eastern slopes of the tropical Andes with its enormous gradient from high altitude “Puna” grasslands and Polylepis thickets to montane cloud forests all the way down towards the tropical lowland forests are known to harbour a rich biodiversity and high endemism of global significance. Despite its small size the property contributes to conserving a very rich habitat and species diversity with remarkable endemic and relict flora and fauna.
