It didn't strike me as being too photogenic, but it was definitely there.
About 7ft tall concrete with razor wire, from the main entrance of MB south right to the new roundabout IIRC (with a gap for that house), and north right to the end of MB.
Maybe some of it used to be there, but I don't remember it, and there is definitely a lot of new.
And it goes much further than the biundaries of MB, even if you take into account the new field they opened last eyar (opp Blue)
Stalag Blanche...
