The Royal Greenwich Observatory

The Royal Greenwich Observatory, established in 1675 in London, was a leading center for astronomical research and timekeeping. It played a crucial role in developing accurate star maps, navigation, and establishing the Prime Meridian (0° longitude), which helps us divide the world into time zones. Over its long history, the observatory contributed to advancements in astronomy, including tracking celestial objects and improving clocks. Though it closed as an observatory in 1998, its legacy continues through its historical buildings in Greenwich, London, and its significant influence on navigation, science, and our understanding of the universe.
