I visited this museum on sunday, at the north end of Ambleteuse, a coastal village between Calais and Boulogne. Entry price is 7.40 Euros per adult and photos are allowed. Presenting your Ambleteuse ticket on entry to the Batterie Todt at Audinghem gets you a reduced entry price there. I will post my photos once I have a CD made up. The web address is http://www.musee3945.com. It has a shop where you can buy some genuine artefacts and plenty of more modern or repro stuff.
