We started the week with a visit to Dover Castle. It was built by Henry II and added to over the years. Henry was very important in our story we learnt about Thomas Becket. We took a tour around the great tower and dressed up in the education centre. We learnt how the castle could hold out against a siege. We also went into the secret war-time tunnels and experienced 'operation dynamo' - you are not allowed to take photos of this!
