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.

Small terrace on the top of the Park Inn, publicly accessible. Take the elevator to the 40th floor, and follow the signs up the stairs. Pay the attendant who also serves beer and coffee. Great views of the Fernsehturm. In the summer, consider base jumping off the roof with Jochen Schweizer. It is often closed in bad/windy weather, so look for a notice posted near the elevator that the terrace is closed.

A small castle in late classical style. It was built 1868 by Martin Gropius (uncle of the Bauhaus-founder and other architects, the von Siemens family changed the castle a bit around 1900 and they enlarged the dimensions of the park, which is today renovated and nice to wander around when the sun is shining. Located within a few minutes' walking distance from Biesdorf station (take the S5 from the city centre) or Elsterwerdaer Platz station (U5).
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.
Arguably the most beautiful bridge in Berlin and the only connection between Friedrichshain and Kreuzberg. As signage on the bridge indicates, it was built twice - once in the 1890s and once in the 1990s. Before reunification the border ran where the bridge now is.
Jewish cemetery and lapidarium with old tombstones.
Official residence of the (largely ceremonial) President of Germany since 1994. Only Roman Herzog (president 1994-1999) actually lived here, his successors have preferred a quiet apartment on the outskirts of Berlin, but this is where the president will usually host guests and do public events. Guided tours are possible, but plan to book up to nine months ahead and be prepared for having to reschedule if the president decides to hold an event on short notice which preempts tours.
In this house the surrender of Germany was signed on May 9th, 1945, ending WWII in Europe.

Historic rooms, permanent exhibition and special exhibits.
The Bierpinsel ("beer brush") is a building in Steglitz which resembles an observation tower and is famous for its pop-art appearance. The futuristic, landmarked building was built from 1972 to 1976 and has since been used as restaurant, night club, bar, radio station and art café.
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.
The main street of former East Berlin. It is a big avenue, featuring neoclassical East German buildings, fountains and lakes.
At a former Luftwaffe and Royal Air Force (RAF) airfield, RAF Gatow. The museum's focus is on military history, particularly the history of the Luftwaffe of the Bundeswehr, with a collection of more than 200,000 items, including 155 aeroplanes, 5,000 uniforms and 30,000 books. There are also displays (including aeroplanes) on the history of the airfield when it was used by the RAF. Aircraft include reproductions of Otto Lilienthal's gliders, of World War I planes such as the Fokker E.III, and World War II planes such as the Bf 109 and Me-262, as well as at least one aircraft of every type ever to serve in the air forces of East and West Germany. Most of those postwar aircraft are stored outside on the tarmac and runways, however, and many are in bad condition. There are long term restoration projects, including a Focke-Wulf Fw 190. RAF Gatow is notable as the "missing third airport" of West Berlin. Each sector used to have its own airport; the French sector had Tegel, the American sector had Tempelhof and the British had Gatow. However, RAF Gatow never saw much traffic of any kind, was more kept as a political statement than for transportation value, and thus was shut down after reunification. Tempelhof, after having been shut down for civilian traffic from 1975 to 1981, closed for all flights in 2008, while Tegel shut down in November 2020.
