Royal Greenwich Observatory

The Royal Greenwich Observatory, established in 1675 in London, was historically a key center for astronomical research and timekeeping. Its main role was to help accurately determine longitude for navigation, which was vital for maritime travel. Over time, it contributed significantly to our understanding of stars, planets, and celestial phenomena, and developed precise time standards. Although its main operations moved from Greenwich, the Observatory’s legacy continues through the Greenwich Mean Time (GMT) and its influence on global navigation and astronomy. Today, the site is home to the Royal Observatory Greenwich museum, celebrating a rich history of scientific discovery.
