On the Belgium coast at Raversijde we see how the WWI Aachen Battery was turned into a section of the Atlantic Wall by the Germans, seeing the bunker, trenches and many original features. We then travel to the French coast for lunch and in the afternoon visit Batterie Todt, a massive bunker that housed a huge artilery piece which bombarded Britain and could be used to fire on any invasion fleet. We see the museum here which includes a very rare German 280mm Railway Gun, then visit the V3 super-gun system at Mimoyecques. Here we go through tunnels built to house this incredible weapon which was never fired in anger due to Allied bombing. We end the day looking at the liberation of the coastal region in northern France in September 1944 with a visit to Calais Canadian Cemetery. (B)
