WATCHTOWER. POTZDAMER PLATZ. BERLIN
Erna-Berger-Straße. 100 meters from Potzdamer Platz. Side road to Stresemannstrasse.
The mushroom-shaped watchtower located at the end of Erna-Berger-Straße is one of the last of its kind. It is a panorama observation tower with an octagonal observation room on top. This kind of tower was introduced in 1969. Because of the narrow shaft, which made it difficult for border guards to turn out quickly, these kind of towers were later replaced by other kinds of watchtower.
Erna-Berger-Straße is a new street built after the fall of the wall. The area was a part of the “death strip” or “no man’s land” between the inner and outer wall. This area was filled with different kinds of obstacles that would hinder an escape from east to west. All the houses in the street were built after the fall of the wall.
The watchtower on Erna-Berger-Straße is listed as an historical monument.
A part of the wall can be seen in the open backyard area opposite the watchtower. There is no access to the backyard but the remains of the wall, approximately 5 meters in length, can be seen through the wire fence.
At the beginning of the street, cobblestones are sunk into the pavement to show the location of the wall. The cobblestones continue inside the building on the south side of the street and a reconstructed part of the wall can be seen through the street windows, also from Stresemanstrasse.
