What features at machu picchu indicate that the incas might have used an astronomical calendar?

Answer 1

Machu Picchu features several architectural elements that suggest the Incas utilized an astronomical calendar. The Intihuatana stone, often referred to as the "hitching post of the sun," is believed to have been used for astronomical observations, marking solstices and equinoxes. Additionally, the Temple of the Sun has windows aligned with the sun's position during key solar events, reflecting the Incas' understanding of celestial cycles. These alignments indicate that astronomy played a crucial role in their agricultural and religious practices.
