The Royal Observatory, Greenwich  

Home of the Greenwich Meridian and Greenwich Mean Time 

Established in Greenwich in 1675, the Royal Observatory moved to Herstmonceux in 1948, where it was greatly expanded and renamed the Royal Greenwich Observatory. In 1990, following a downsizing, it moved to Cambridge where it remained until it was closed down by the Particle Physics and Astronomy Research Council (PPARC) in 1998.
