A huge mysterious door-like structure in the Hayu Marca mountain region of Southern Peru near Lake Titicaca, 65 kilometres from the city of Puno, has long been revered by local indians as the "City of the Gods." Although no actual city has ever been discovered, it is part of an area known as a Valley of the Spirits, or Stone Forest, made of strange rock formations that resemble animals, beings, buildings, dinosaurs, and artificial structures. The door or the "Puerta de Hayu Marca" (Gate of the Gods) has been, at some time in the distant past, carved out of a natural rock face and in all, measures exactly 23' in height and width, with a smaller alcove in the center at the base which measures in at just under 6' in height.
The native indians of the region had a legend that spoke of "a gateway to the lands of the Gods", and in that legend, it was said that in times long past great heroes had gone to join their gods, and passed through the gate for a glorious new life of immortality, and on rare occasions those men returned for a short time with their gods to "inspect all the lands in the kingdom" through the gate.
According to some individuals who have lain their hands on the small door, a feeling of energy flowing has been commented on as well as strange experiences such as visions of stars, columns of fire, and the sounds of unusual rhythmic music. Others have said that they have perceived tunnels on the interior of the structure, although nobody as yet has found a gap that would illustrate the door opening. On the contrary the professional opinion is that there is no actual door, for the frame and the entranceway and the back of the alcove are all carved from the same rock.
