The fort has seen real battle and the building testifies to that - battered walls, uneven wet floors. However that means it is not a comfortable place to visit and not one to linger. There is lots of info on the audio guide, but you don't really feel you want to stand long in a damp, cold corridor to listen. We did look round to take in the main points but kept our visit brief. The area surrounding the fort has been heavily shelled so the ground is very uneven from the craters, which again is interesting but means care needs to be taken walking around.
