In a quiet corner of Berlin stands a colossal concrete cylinder, built during the Second World War to answer a single question: could the city’s ground support monumental architecture? The structure was completed in 1941 as a test site for planned buildings in Albert Speer’s grand redesign of Berlin, often called “Germania.”
The construction is simple yet staggering: a 12,000-ton block of concrete, 15 meters high and 20 meters in diameter. Engineers used it to test how Berlin’s subsoil—mostly glacial sands—would react under extreme pressure. The results were sobering. The ground sank, proving unsuitable for the colossal projects envisioned for the city.
When the war ended, the test cylinder remained. Its mass made demolition impractical, and so it stayed, weathering decades of change. Today, it stands as a stark and unusual relic of the Third Reich’s architectural ambitions—less a ruin than a raw piece of engineering left in place.

150-200 m along the Wiener Straße (bypassing the fire house and the public swimming pool) from U-Bahn Görlitzer Bahnhof, the park is famous for the Turkish families barbecuing on summer weekends, failed contemporary art and relaxed atmosphere of students. It does have a reputation of being full of pickpockets and drug dealers though and the police makes regular visits to this place to check on the situation.
German historical museum covering everything from pre-history up to the present day. One can spend many, many hours here! The building from 1695/1730 was the Zeughaus (Arsenal) until 1876.
A man-made hill of about 120 m in the Grunewald, created after the Second World War from debris of the city. On top is the Field Station Berlin, a former US listening station. Inside the building complex you can see lots of graffiti art. The hill can be accessed without any restrictions and is free; however, the building complex is surrounded by fences and requires a ticket (tours are available as well).
A cuboid made of concrete. On the front side of the cuboid is a window, through which visitors can see a short film of two kissing men. The video will be changed every two years and will also show kissing lesbians.
The largest aquarium in Germany with over 9000 animals that are presented on three storeys in a historic building. Aquarium Berlin is found on the premises of the Zoo, but can also be visited separately. One of the best places on a rainy day with children.

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.
Also known as "der hohle Zahn" (the Hollow Tooth), this church in Breitscheidplatz is a memorial to Kaiser Wilhelm, and one of Berlin's most famous landmarks. Thick walls and plain decor mark it as neo-Romanesque, but with what's left of the Gedächtniskirche, it's tough to distinguish it as any one style. Allied bombing left only one tower standing on 22 November 1943, but a new location for worship designed by Egon Eiermann was completed in December 1961 (it's the octagonal structure with blue stained glass windows). There is a small memorial museum beneath the tower filled with artifacts from the original church, which was built from 1891-95 to architect Franz Schwechten's specifications.Controversy arose after the war over the various options presented by the half-ruined cathedral - should it be torn down completely and rebuilt? Or should the destroyed sections be left standing as a memorial? The four major sections of the Kaiser-Wilhelm-Gedächtniskirche (central space, foyer, new tower and chapel) surround the ruined tower of the old church bridge and show the time gap between old and new. Mosaics and other remnants from the old church serve as a monument against war.
It is the only hemp museum in Germany; you can see the history of hemp, the culture and use of it. You can see hemp grow. There is a cafe downstairs, with an open WiFi access. Everything going on here is legal - including the hemp growing under artificial light (a low THC strain grown with a special permit) - but they do not refrain from political commentary on the legal situation of cannabis in their exhibits.
One of the oldest buildings in Charlottenburg and actually the reason for the whole city to be built.
Want to feel like one of the angels in Wim Wenders' classic film Der Himmel über Berlin (a.k.a. Wings of Desire)? Climb to the top of Gold-Else, as the statue of Victory on the top of the Victory Column is known. Just don't jump off if you're not actually an angel. Unfortunately there is no elevator, so be prepared for 285 steps to the platform at 50.7 m.Else was built to commemorate Prussian military prowess in the wars against Denmark (1864), Austria (1866) and France (1870-71), and moved to her present location by the Nazis. Five roads run into a traffic circle called Grosser Stern, in the centre of which is the Siegessäule. Else is visible from much of the city district known as Tiergarten. At the base of the statue are reliefs of war scenes representing the conflicts which this monument memorializes. The Allies forced Germany to take those panels down in 1945, but they were remounted in 1984 and 1987. It also served as a backdrop for a speech by then senator Obama in 2008, after his request to speak in front of Brandenburger Tor caused a political debate in Germany.
