Underworlds’ FAQs Answers to frequently asked questions


Do I have to make an advance booking for the underground tours?

Advance bookings are not possible yet. Tickets for tours 1,2,3 and M are sold on the day, at our ticket shop near the southern entrance of Gesundbrunnen subway station (U8) at Brunnenstraße 105. Please buy your tickets at least 15 minutes before the scheduled starting time. It is a good idea to arrive early, especially in the summer, as tours can sell out.

Tickets for tour F are sold on the day, from 15 min. before the tour starts at the entrance of the building at Fichtestraße 6, Berlin-Kreuzberg.


What kind of clothing is recommended for the underground tours?

There are no special recommendations for Tour 1 and Tour 3. However, please be aware that it is always a little bit chilly underground. The lighting is sufficient and our structures are dry.
For Tour 2 – “From Flak Towers to Mounts of Debris” – sturdy footwear is required and warm clothes are recommended! The temperature within the Flak Tower is 10° Celsius at best, even in the summer, and the humidity is considerable. Helmets are provided by the Berlin Underworlds Association.
For Tour F – “The Fichtebunker time capsule” and Tour M – “Under the Berlin Wall” warm clothes are recommended!


May I film or take photos during a tour?

Photography and filming are generally not permitted.

In the past we have observed that photography and filming can considerably disrupt the flow of the tours. Additionally, we have a number of artifacts on display that are on loan from eye-witnesses, whose copyright and right to privacy has to be protected. We are happy to provide professional press photos on request for a specific publication.

Producers of professional TV-documentations should check our production notes and contact us via our contact form.


Is it possible to rent Berlin Underworlds Association’s locations for private parties?

No, it isn’t. Berlin Underworlds Association is a non-profit organization. However, we do support cultural activities in the Underground. If you want to organize a cultural project in Berlin's Underworlds, please contact us and provide us with a short presentation of your intentions.


Is it possible to order literature about underground topics from the Berlin Underworlds Association?

Yes, it is.
Please find the selection of books we offer in our shop-section (German). For orders outside Germany, we require payment by bank transfer in advance.
Many of the books are also available at our ticket shop at Berlin-Gesundbrunnen.


Where is the “Fuehrerbunker” (Hitler’s bunker) and can it be visited?

The remains of the so-called “Fuehrerbunker” are situated beneath a parking-lot on the corner of “Gertraud-Kolmar-Strasse” and “In den Ministergaerten”, and marked by an information panel that our Association provided. During the Cold War, the site was next to the Berlin Wall, the border area between East and West Berlin. In 1988, some pioneers of the East German National Army excavated the bunker and filled it in. Today, there are just a few fragments of the floor and parts of the walls under the ground but no hollow spaces whatsoever. It is absolutely impossible to visit the “Fuehrerbunker”.


Does Berlin Underworlds Association organize tours in Berlin´s sewer system?

No, it doesn’t. The Berlin Waterworks Company is in charge of sewers and they are normally not open to the public, with a few exceptions – on the Day of Open Doors or Heritage Day, for instance. However, you will see pictures of the subterranean Berlin Wall in the sewers on Tour M – “Breaching the Berlin Wall”. Some aspects of the Berlin sewer system will be touched upon during Tour 1 – “Dark Worlds”.
More information about the sewer system can be found at the Waterworks Museum in Berlin-Friedrichshagen (German language only)


Where can I get information about tunnel walks or open-top subway tours?

The Berlin Transit Authority (BVG) is in charge of these activities.
Please take a look at this website (German).
