The Menin gate is something else. In Ypres they've made efforts to preserve the trenches in a relatively historical condition. It's a good idea of what they were like - without the obvious fears.
I went to The Somme with my school years ago. During the day, I saw some kids throwing stones at an object on a wall. I looked more closely and it was a hand grenade! Somebody has uncovered it, put it on the wall and left it there. Needless to say, I left. Quickly.
If you ever get a chance, visit the war cemeteries on both sides. The Allied graves are beautiful and sombre places. The graves of the German allies are entirely different - rather than open, wide spaces, they are much more compact - at least the one I visited was. A very stark contest and one that is harrowing but historically important.
