About

The Royal Observatory Greenwich is the historic home of British astronomy, Greenwich Mean Time and the Prime Meridian of the world.

The Royal Observatory was founded by Charles II in 1675, and now welcomes visitors from around the globe to stand at the centre of world time.

In 2025 the Royal Observatory is celebrating its 350th anniversary.

Observatory curators and astronomers are hosting a season of special events to mark this historic moment, from astronomy live streams and stargazing demos to author talks, family activities, sessions for schools and much more.

You'll even be able to travel back in time, and see what the night sky would have looked like 350 years ago in a brand-new show at London's only planetarium!

Come and celebrate 350 years of the Royal Observatory, and discover the past, present and future of the Home of Time.
