World War II Bunkers
One of the focal points of Berliner Unterwelten is the network of bunkers built during World War II.
These bunkers served as shelters for civilians during air raids and as command centers for military operations.
Traversing the winding passages and rooms unveils numerous war artifacts buried for decades, depicting the daily life of ordinary Berlin citizens during air raids that devastated 80% of the city center.
Exploring bunkers reveals wartime Berliners’ lives and measures taken for population protection.
The Fichtebunker
Representing 130 years of Berlin history, the Fichtebunker, initially a gasometer, transformed during the Nazi era into a six-storey “mother and child bunker.”
Providing refuge for thousands during air raids, it later became a Red Army occupation site, post-war reception center, prison, retirement home, and homeless shelter.
In 1963, after serving as the “Bunker of the Hopeless,” it stored food reserves for West Berliners.
The original interior serves as an exhibition space for Berliner Unterwelten, exploring the building’s structure, technology, and the tragic wartime experiences of refugees and the homeless through exhibits, eyewitness accounts, and projection technology.
Cold War Bunkers
As the Cold War unfolded, Berlin became a hotspot for geopolitical tensions.
The divided city saw the construction of additional underground facilities, including bunkers and escape tunnels.
Berliner Unterwelten reveals East and West Germany’s strategies against potential conflicts and nuclear warfare threats.
The civil defense shelter “Blochplatz,” an air-raid shelter renovated in the early 1980s from World War II, was designed to accommodate 1,318 people for up to 48 hours in case of an emergency.
A brief “U-Bahn” ride to Pankstrasse station reveals the workings of a “modern” bunker, constructed in 1977 during the northbound extension of the U8 underground line.
Moreover, “U-Bahn” refers to the underground railway system in Berlin, Germany. Specifically, it is a shortened form of “Untergrundbahn,” which translates to “underground railway” in English.
This versatile facility, not only serving as a U-Bahn stop for commuters but also intended to protect West Berlin citizens during a potential nuclear war, could have housed 3,339 people for up to two weeks in case of an emergency.
