Essential information

Location

Download the free Royal Observatory audio guide, pop in your headphones and learn all about the home of Greenwich Mean Time... in your own time.

And while the Royal Observatory is temporarily closed for a landmark transformation project, this is your opportunity to explore the historic site remotely!

We're used to planning journeys and navigating new places with our smartphones, but none of that would be possible without the work of the Royal Observatory.

Pioneering telescopes and timepieces – and the people who designed and used them – helped us find our place in the Universe, and put Greenwich at the heart of time, space and navigation.

But how did Greenwich become known as the 'Home of Time'?

The audio tour is free to all. All you need is your phone and headphones.
