A marking on the ground shows where the Berlin Wall once cut through the heart of the city, dividing East and West Berlin.

A specific marking on the ground identifies the exact location where the Berlin Wall previously intersected the center of the city. This historical boundary once served to divide East Berlin from West Berlin, creating a physical separation between the two sectors. The current ground markers preserve the memory of this division, illustrating the path the wall took through the heart of the city to separate the eastern and western regions of the German capital.
