Meistersaal

It was a museum of applied arts and a listed historical monument since 1966, and it is now a well-known Berlin exhibition hall.

This outdoor and indoor history museum documents the terror applied by the Nazi regime. It is on the site of buildings which during the Nazi regime from 1933 to 1945 were the headquarters of the Gestapo and the SS, the principal instruments of repression during the Nazi era.

Huge technical museum, on a former railroad depot, featuring from ancient water and wind mills to computer pioneer Konrad Zuse's inventions, a collection of old to new vehicles of all types -bicycles, boats, trains, etc - and the interactive Spectrum science center with various hands-on experiments. There's an actual C-17 "Candy Bomber" airplane hanging on its façade. The railroad and aeronautical sections are hard to beat.

It was the only border crossing between East and West Berlin that permitted foreigners passage. Residents of East and West Berlin were not allowed to use it. This contributed to Checkpoint Charlie's mythological status as a meeting place for spies and other shady individuals. Checkpoint Charlie gained its name from the phonetic alphabet; checkpoints "Alpha" and "Bravo" were at the autobahn checkpoints Helmstedt and Dreilinden respectively. Checkpoint Charlie's atmosphere was not improved at all on 27 Oct 1961 when the two Cold War superpowers chose to face each other down for a day. Soviet and American tanks stood approximately 200 m apart, making an already tense situation worse. Now the remains of the Berlin Wall have been moved to permit building, including construction of the American Business Center and other institutions.
At the intersection of Zimmerstraße and Friedrichstraße (U-Bahn Kochstraße U6) is the famous "You Are Leaving the American Sector" sign. The actual guardhouse from Checkpoint Charlie is now housed at the Allied Museum on Clayallee. For a more interesting exhibit go to the Haus am Checkpoint Charlie. This is a private museum with kitschy memorabilia from the Wall and the devices GDR residents used to escape the East (including a tiny submarine!). There are also people who set up booths here offering to stamp your passport with souvenir stamps in exchange for a small fee. You are highly advised not to put these stamps in your passport, as these are not official stamps and could invalidate it. Instead, bring along an expired passport or a small booklet to put the stamps in.

Designed by Daniel Libeskind with an excellent exposition on the Jewish life in Berlin and the impact of the Holocaust. You can easily spend a day here. There is a metal scanner and other security features you'd rather expect at an airport than a museum.

Take a stroll for a few kilometers along this canal which runs right through the heart of Kreuzberg. It's peaceful and mostly traffic-free, but full of life in summer. Some parts are lined with bars and restaurants with terraces. Sit on a bench or terrace and watch the world go by on a summer evening.
