At the former border checkpoint known as the Tränenpalast, millions of people once parted ways. Travelers leaving East Berlin by train would exchange hurried hugs and last looks, while friends and relatives from the East stayed behind. The name, meaning “Palace of Tears,” hints at the emotions captured by this place.
After the Berlin Wall fell, the building took on a surprising new role. Less than a year later, it became a nightclub, a symbol of the city’s sudden shift from division to freedom. Music and late nights filled a space once defined by strict controls and separation. The club closed in 2006, ending a brief but memorable chapter.
In September 2011, the Tränenpalast re-opened as a museum. Today it hosts a permanent exhibition that reconstructs the routines and rules of life in a divided Berlin. Passports, inspection booths, and personal stories show how border checks shaped ordinary days. The displays reveal how an extraordinary system became daily reality—and how that reality left a lasting mark on the city.

Berlin's biggest lake and popular resort for bathing and watersports. You can also travel there by tram, which is an experience by itself.
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.
The last Mies van der Rohe building (a dwelling house) in Germany before his emigration to the U.S. (1938). Now there are small contemporary/modern art exhibitions.
More than 30 million objects in the scientific collection and a fascinating exhibition in one of the most significant institutions of its kind in the world. Some parts still under construction.
The meeting point of one of the leading oppositions against the GDR regime and is a great Neogothic church. Also the only ecumenical Lord's supper with Protestants and Catholics together took place in the Gethsemanekirche (2003).
In 1893 the authorities of Berlin issued the artistic entrance to the National Park Friedrichshain. The fountain of fairy tales was commissioned by the National Park and later designed by Ludwig Hoffmann.
The longest moving refracting telescope is 21 m long with a lens diameter of 68 cm. This giant telescope was built in 1896 by Dr. Freidrich Simon Archenhold but is now part of the Deutsches Technikmuseum Berlin. It was the place where Albert Einstein presented his Theory of Relativity to the public in 1915.
This heritage-protected 120-m-long pedestrian tunnel below the river Spree was the first ferro-concrete tunnel in Germany that has been built using pneumatic caissons. Two beaches can be accessed via the tunnel which are not far from its south entrance.
The building houses the personal offices of the Chancellor and the Chancellery staff. The Berlin Chancellery is one of the largest government headquarters buildings in the world. By comparison, the new Chancellery building is ten times the size of the White House. A semi official Chancellor's apartment is on the top floor of the building. The 200-m², two-room flat has thus far only been occupied by Gerhard Schröder chancellors since then have lived elsewhere. It is usually not possible to visit the building, but on occasion there are tours, usually around August. The building was deliberately designed in a way to symbolize the German constitutional system - it's in the line of sight of the Bundestag and lower in height, symbolizing the role of parliament in controlling government and "the people's house" being the higher power in the relationship between the two. Or at least that's the idea.
The building of one of Berlin’s oldest breweries is a ravishingly beautiful and heritage-protected industrial monument.
A domed church at Bebelplatz/Unter den Linden, the oldest (mid-18th century) and one of the biggest Catholic churches in Berlin. Interior was redesigned in a modern style in the 1950s, but there are still many treasure chambers in the basement.
The Bayerischer Platz is the centre of the Bayerisches Viertel ("Bavarian district", with many streets named after Bavarian cities), which was destroyed a lot more during World War II (about 60%). Somewhere around there Albert Einstein lived once. You’ll find several memorial signs providing information about the Nazi regime's persecution of gays and Jews.
