Gosh, and all this time I thought the East Berlin wall was to keep people IN . . .
Seems to me that was the objective. Visited near the border between the west and east again in ‘68 when I was in the Navy. No crossing that time. ;-)
East Berlin had a wall that ran around its entire perimeter, even on the east side, to Keep East Germans OUT. It was a showplace for them, in “The Worker’s Paradise”.
The wall around West Berlin was 110 miles long. We had 5 days to run every mile of it.
