Robert Hume, head of history at Clarendon House Grammar School, Ramsgate, has taken pupils to Dover for the past 14 years
Year 9 pupils focus on the Second World War and the tunnels. We set up connected activities. Last year we had a "Blitz Experience", "Rationing", and "Make Do and Mend" - pupils learned how to darn socks, knit a scarf and make tablets of soap. We hire the classrooms housed in the inner curtain wall. The tunnels are the jewel of the visit and something is added each time we go. Walmer Castle has interesting artefacts and the gardens are ideal to picnic in.
