ancient observatories
Old sky-watching sites
Ancient observatories are structures built by early civilizations to track celestial movements—the sun, moon, stars, and planets.
Sites like Stonehenge, Chichen Itza, and the Jantar Mantar aligned with solstices, equinoxes, or specific stellar events.
These served practical purposes: marking agricultural seasons, creating calendars, and timing religious ceremonies.
The ancient observatory at Angkor Wat marks the spring equinox.
