Berlin sculpture

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.

Erected in 1818 to a classically-inspired design by Karl Friedrich Schinkel as a guardhouse for the imperial palace, since 1993 this compact building has housed a small, but extremely powerful war cenotaph, the Central Memorial of the Federal Republic of Germany, continuing its use under East German rule as the primary "Memorial to the Victims of Fascism and Militarism". The interior of the Doric column-fronted building is intentionally empty, but for a small but moving sculpture by Käthe Kollwitz depicting a mother cradling a dead child. The statue is positioned beneath a round hole in the ceiling, exposing the figures to the rain and snow.

This area was Gay Central during the Weimar Republic, and it is today. But of course all are welcome. There is a diverse mix of restaurants and stores, several of which are open till midnight or later every day. The U-Bahn station has a superstructure and towers that echo the appearance of the Art Nouveau Neues Schauspielhaus across the street, now the Metropol, where radical left-wing dramas used to be presented in the 20s and 30s, and it is lit in rainbow colors.

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.

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.

This imposing building houses the Federal German Parliament or "Bundestag" and was completed in 1894 to meet the need of the newly-unified German Empire of the Kaisers for a larger parliamentary building. The Reichstag was intended to resemble a Renaissance palace, and its architect, Paul Wallot, dedicated the building to the German people. The massive inscription in front still reads: "Dem Deutschen Volke" - 'For the German people'. The Nazi leader Adolf Hitler exploited the fire which gutted the Reichstag building in 1933 by blaming the Communists for the arson and for attempted revolution. There is good evidence to suggest, however, that his followers were actually responsible and that this was a manufactured crisis. The iconic photo symbolizing the Soviet victory over Nazi Germany shows a Soviet soldier planting the Soviet flag on top of the building and there are to this day graffiti left by Soviet soldiers on some walls of the Reichstag which were deliberately preserved by the new Germany as a memento of the war. It's perhaps the only national parliament to have traces left by a foreign army deliberately preserved. When German reunification became a reality, the new republic was proclaimed here at midnight on 2 October 1990. The Reichstag building is well-known in the art world thanks to Paris-based Bulgarian artist Christo's mammoth 'Wrapped Reichstag' project in 1995. The entire building was swathed in silver cloth for two weeks that summer.The Reichstag has undergone considerable restoration and alteration, including the addition of a spectacular glass dome designed by the British architect Norman Foster completed in 1999. You can visit the Reichstag building proper and even listen to a parliamentary debate but you need to book on their website sometimes weeks or even months in advance. Fortunately its much easier to visit the glass dome. You can reserve a visiting time and date on their website or in the small building across Scheidmannstrasse, except during the high season you should be able to arrange a time later the same day or the next day. Photo ID or passport is required to make the booking. A passsport is required during your visit. This is a very popular tourist attraction in Berlin and can get quite crowded however it is worth the effort. The helical path up the inside of the dome is a lot of fun and the 360 degree views at the top are splendid.

The memorial site stretches along the full 1.5-km length of Bernauer Straße. The listing marker points to the visitor centre. Various monuments can be found along the entire length of the street, documenting nearby escape attempts and tunnels; captions are in German and English. The documentation centre across the street on Bernauer Straße/Ackerstraße is excellent (although most of the documentation is in German). The viewing platform next to the documentation centre gives you a tiny hint of the true scale of the Wall and how terrifying the "no man's land" between the two sections of walls must have been. The monument (that you can see from the platform) is a complete section of 4th generation wall - both inside and outside sections, and you can peer through from the east side to see the remains of the electric fence and anti-tank devices in the death strip. It really helps you understand what an incredible feat it was to get from one side to the other -- and why so many died doing it. The memorial site is often missed by tourists but an absolute must for anyone interested in this part of the city's history. It's a memorial to those who died crossing, so you won't, fortunately, get the tackiness of the Checkpoint Charlie area; instead you will be left with a haunting feeling of what life with the wall may have been really like.Bernauer Straße is a street with a great deal of Wall history: it came to tragic prominence on August 13, 1961 when East German authorities closed the border and the street (with houses in the East but the street in the West). Border guards walled the doors and windows shut to keep Easterners from escaping by jumping out the window while Westerners (including police and fire brigades who brought life nets to help catch refugees) looked on in horror. The first recorded Wall-related death - the notorious Peter Fechter case (he bled to death in the "no-man's-land" with both sides unwilling or unable to help him) - was here, as was one of the famous tunnels and the famous photograph of the GDR border guard leaping over the barbed wire.

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.

Not far away from Schloss Tegel (at the "große Malche") you can take a look at the oldest tree in Berlin, an oak which has been growing there since about 1192 (so it's actually older than Berlin itself). The name ("fat Mary") allegedly stems from the brother Humboldt who named the tree after their overweight cook.

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.

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.

Includes East Asian and Indian sections.

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

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.

From 1941, 12,000 tons of concrete in a 15-m-high and 20-m-diameter cylinder were built to test the load-bearing capacity of the Berlin soils (turns out glacial sands are no good basis for gargantuan architecture) for Albert Speer's Germania buildings. Too massive for later blasting, this is one of the more bizarre remains of the Third Reich.

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.
