Royal Observatory, Greenwich

The Royal Observatory, Greenwich is the home of Greenwich Mean Time and the Prime Meridian of the World, making it the official starting point for each new day and year. It is also home to London's only planetarium, the Harrison timekeepers and the UK's largest refracting telescope.

Designed by Wren, the Royal Observatory is the original home of the Astronomers Royal. Most visitors come to stand on the Greenwich Meridian Line, longitude zero, which divides East and West and to see the real time ball which has fallen punctually at 13.00 every day since 1833.

Please see the website for regular events and shows happening throughout the year.
