1. Royal Observatory Greenwich — Greenwich Park
Stand astride the Prime Meridian, home of Greenwich Mean Time.
The Royal Observatory, at the top of Greenwich Park, is where the Prime Meridian of the world runs. You can stand with a foot in each hemisphere, see historic timekeepers and visit the Peter Harrison Planetarium.
The views over the Queen's House, the Old Royal Naval College and Canary Wharf are superb.
Good to know: Book a planetarium show to combine with your visit.
