What's happening?

The Royal Observatory Greenwich will be closed for essential refurbishment from 4 January until 31 March 2022.

This is part of an exciting redevelopment project taking place at the home of Greenwich Mean Time.

Visitors will not be able to access the historic buildings, Observatory galleries or the Prime Meridian Line during the closure period.

Our expert astronomers however will continue to guide visitors through the wonders of the night sky, both online and at the Observatory itself.
