hi, we are passing through from Calais on way to Spain in july. We have 5 weeks so no rush so wanted to find some WW1 museums up North to visit en route. I have children and me and my son enjoy the WW2 stuff that we have been to and we have also been to Oradour Sur Glane. can anyone recommend and museums with good displays of WW1 equipment etc and ideally a replica trench set up that is worth a visit. Thanks
