Embark on your journey through time
Ever wondered what the famous pip-pip-pips sound heard on BBC radio marking the hour is?
Make time to find the master clock at the heart of Britain's time system (and much of the world's) for many a year.
Don't miss this pocket watch that spent 12 days in the water after the Titanic went down.
This clock was used as The Sidereal Standard at the Royal Observatory, Greenwich for over 50 years until it was superseded in 1922.
In 1967, the world changed and time became a matter of atoms rather than stars.
Treat yourself to a fine afternoon tea or relax with a frothy coffee at our cafes and restaurants. Go on, you deserve it.
