Royal Observatory, London

The Royal Observatory is an iconic scientific landmark nestled in the heart of Greenwich, London. Established in 1675 by King Charles II, it is famed for being the location of the Prime Meridian, where time begins at longitude 0°. The observatory played a pivotal role in the history of astronomy and navigation, and today, it serves as a museum and educational center that fascinates tourists and astronomy enthusiasts alike.

Visitors to the Royal Observatory can stand on the world-famous Meridian Line, which divides the eastern and western hemispheres, and capture a unique moment in time and space. This historical site is also home to the historic Harrison timekeepers and the Great Equatorial Telescope, one of the largest of its kind in the world. The observatory's Time and Longitude galleries delve into the story of how scientists have measured time and space, from the earliest days of astronomy to the modern era.

The Royal Observatory also boasts the Peter Harrison Planetarium, a state-of-the-art facility that offers a captivating journey through the stars and beyond. The planetarium's shows are both educational and entertaining, providing a glimpse into the wonders of the universe.

For those interested in the practical side of timekeeping, the observatory is also the source of Greenwich Mean Time (GMT) and the 'pips' that signal the precise start of each hour on BBC radio. This connection to everyday life underscores the observatory's enduring relevance.

The Royal Observatory is situated within Greenwich Park, offering spectacular views across London. Visitors can explore the historic Flamsteed House, designed by Sir Christopher Wren, where the Astronomers Royal once lived and worked. The Camera Obscura installed here provides a unique visual experience, projecting a panoramic view of the surrounding area.
