In the Peruvian Andes, on a mountain saddle, about 400 meters above the Urubamba River, there is a mysterious abandoned village, the existence of which for a long time no one knew. It is now called Machu Picchu (Machu Picchu - Old Peak), by the name of the mountain located next to it, but no one knows what its former inhabitants called this village. Machu Picchu is sometimes called the "lost Inca city." This city was created as a sacred mountain refuge by the great Inca ruler Pachacutec a century before the conquest of his empire, that is, approximately in 1440, and functioned until 1532, when the Spaniards invaded the territory of the Inca empire. In 1532, all its inhabitants mysteriously disappeared. By its modest size, Machu Picchu cannot claim to be a large city - there are no more than 200 structures in it. These are mainly churches, residences, warehouses and other facilities for public use. For the most part, they are made of well-crafted stone, tightly fitted to each other slabs. It is believed that up to 1,200 people lived in and around it, who worshiped the god of the Sun Inti there and cultivated crops on the terraces. Machu Picchu was a beautiful city with cult buildings and palaces, gardens and earthen terraces, irrigation canals, wells and baths, and in the plots cultivated corn, ovogtsi and potatoes. Terraces located at different levels were connected to each other by a system of stairs. The Spanish conquerors did not know about Machu Picchu and did not get here. Nevertheless, for unknown reasons, the city was suddenly abandoned by its inhabitants. The beauty of Machu Picchu, indeed, is beyond doubt. The real name of Machu Picchu, like many other things in his fate, is still shrouded in obscurity.
