Berlin Wall History Mile at the Invalidenstrasse border crossing

There are two Berlin Wall History Mile info boards at the former Invalidenstrasse border crossing (west of the Sandkrugbrücke on the sidewalks to the north and south). One describes a failed escape attempt from 1963, while the other tells the story of Günter Litfin, who tried to escape from East to West Berlin through Humboldthafen, a nearby port, eleven days after construction on the Berlin Wall began.
