Having seen a few, there is nothing "written" on the inside of the gates of concentration camps. The words, "Arbeit macht frei" (Work will make you free, perhaps offering the false impression that those who were taken to the camps could earn their freedom) is worked into the ironwork above or near a number of the gates of several camps, and perhaps the Nazi's were trying to calm the masses coming into the camps to make it easier to control them.
Allied troops would approach, if the gates were not opened for them, then they would open them.
Of course they couldn't. Not only were the camps in the middle of nowhere, but they were surrounded by gates with barbed wire on top, and guards. It was pretty much a concentration camp without the killing. Most of the time.
The number of gates you will need for a new camp will depend on the size of the camp. Small camps only require one gate while larger camps may need two, three, or more gates.
fences, electric fences, some had stone walls, human guards, guard dogs, lights, alarms, gates, barbed wire and collective punishment. To name a few
To keep people out that are not supposed to be inside of the logics. If people get inside of the Logic gates, they could cause havoc to the people inside of these gates.
