The red areas are prisons. The one on the north is the Verne Citadel, now a prison. Not sure what the other is, but it looks like a prison from the air, and google street view shows a sign on the front entrance that says "prison facility". Don't know how up to date the maps are. I would assume both are active, and stay WAY away from them.
That's bad luck about the Verne Citadel, that place would have been a GREAT piece of history to display. Unfortunately, messing with it is likely to get you a full time view. From inside.
