Royal Engineers Museum, Chatham, Kent

The museum contains exhibitions and displays about military engineering. There are also vast reserve collections for researchers. FYI military engineers build camps and fortifications, dig tunnels etc.
On the day I visited there was a progamme of re-enactments before the front of the building – soldiers attacking, defusing bombs etc. Interesting, but a bit of a distraction from trying to get round the four sides of the galleries and see the exhibits.
