A very interesting and compact site which illustrates some important facts about the Ypres Salient and the fighting in it. There is a German bunker, which British troops took over and added to. It was also used in the Second World War. The remains of the craters can be seen, which were the product of the work of tunnelling experts. The best preserved is Caterpillar Crater in private grounds across the railway line. Facing the road is a memorial to the Australian tunnellers.
