Preserved sections of the outer wall Topography of Terror

A 200-meter-long section of the “Grenzmauer (border wall) 75,” the fourth version of the Berlin Wall used from the mid-1970s onwards, stands on Niederkirchnerstrasse on the grounds of the Topography of Terror documentation center. Souvenir hunters chipping off bits of the concrete in 1989 and 1990 left deep gashes in this section of the wall, which today is protected by a fence.
