The researchers report that Inca astronomers could have watched and tracked a number of astronomical phenomena from the area, including summer and winter solstices and the movement of the moon.
According to the investigators, Intimachay was likely a sacred space. Another observatory was confirmed in the Inkaraqay area, which is located on Huayna Picchu. The most interesting thing about the research, perhaps, is the technology used to carry it out.
Peruvian journal reports that the international team used 3D scanning software to analyze the structures and compare their shape and placement with the positions of the stars as would have been seen by the Incas. El Comercio writes that this discovery is the first time that the existence of Inca astronomy has been confirmed, even though it was described as early as 1572 by chronicler Sarmiento de Gamboa.
