Churchill tank
The wall is about long, high by wide. It is divided into two sections between which there were originally steel gates. Nearby are other obstacles such as dragon's teeth, reinforced concrete blocks and lengths of railway track set in concrete and with wire entanglements. Many of the relics show signs of live weapons training and the main wall has two breaches caused by demolition devices including the Double Onion: a specialised demolition vehicle, one of Hobart's Funnies, based on the Churchill tank.
