Old Royal Observatory

The Old Royal Observatory, located in Greenwich, London, was established in 1675 to improve navigation at sea through better star and planet measurements. It became famous for its role in developing accurate timekeeping and international standard time (Greenwich Mean Time). The observatory's astronomers made important discoveries about the motion of celestial bodies and helped map the stars. Today, it functions as a museum and educational site, where visitors can learn about astronomy, navigation, and the history of science, while enjoying panoramic views of London from its historic vantage point.
