Inside The Tower of London: Building the World's Greatest Castle

The Tower of London is one of the most famous buildings in the world. But many people don't realise that it's more than just a single castle. From the Bloody Tower to Traitors' Gate, it's a vast and sprawling complex of towers, chapels and royal apartments. But who built all the different parts of this palace, when did they build them, how and why? In this special episode of Inside the Tower of London, BAFTA award-winning actor Jason Watkins and historian Tracy Borman explore how the Tower was transformed from a single keep to an epic fortress spanning 12 acres. With the help of cutting-edge 3D graphics, we recreate what the Tower would have looked like through the ages and chart its evolution over a thousand years.
