1. Synchronise your watches at The Royal Observatory
The Royal Observatory in Greenwich is a must see. Explore your place in the universe in the great Onion Dome (originally made from papier mâché!) and take a look through the colossal telescope that took 8 years to build. Learn all about time and space, kickback in the Planetarium, stand astride the Prime Meridian or enrol yourself on an Astronomy Course. You will find plenty to do for all the family.
