Our walk today takes you back through two thousand years of London's history – to the era when it was the great Roman colonial city of Londinium! And we will be walking in the footsteps of the people who made London great! We'll tread on the floors of the actual houses where Roman settlers lived! We'll stand where C11th King William the Conqueror stood, when he planned the mighty fortress and palace from which he would rule England. Along the way we'll see the mightiest fortress of medieval Europe, and London's most famous bridge – Tower Bridge!
