On the sign:
The Greenwich Meridian Telescope
Behind the window is the telescope which defines the Greenwich Meridian. It is a transit circle designed by the 7th Astronomer Royal, George Airy, in 1850. It was the centre-line of this instrument that was adopted by an international conference in Washington, USA, in 1884 as the Prime Meridian for the World, or longitude 00° 00’ 00". Both time and longitude are measured from this line.
