Schloss and Schlosspark Biesdorf

A remarkable medium-sized classical castle by the famous K.F. Schinkel built 1820 to 1824, also called "Humboldtschlösschen", because Alexander and Wilhelm von Humboldt (and their family) lived here once. Still privately owned.

The town hall of Berlin is known as such because it is made of red brick, not due to its former political persuasion. There are nice Prussian rooms inside, which are worth a look.

Berlin's biggest lake and popular resort for bathing and watersports. You can also travel there by tram, which is an experience by itself.

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.

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 only surviving Berlin city gate and a potent symbol of the city. This is the point where Straße des 17. Juni becomes Unter den Linden. The gate was designed by Carl Gotthard Langhans in 1791 and was intended to resemble the Acropolis in Athens. The Brandenburg Gate now symbolizes reunification, after dividing East and West Berlin for decades. This is the site of Reagan's "Mr. Gorbachev open this gate, Mr. Gorbachev tear down this wall" speech.

Germany's national centre for contemporary non-European art. The house is a leading centre for the contemporary arts and a venue for projects breaking through artistic boundaries. This architectural landmark was an American contribution to the international building exhibition INTERBAU 1957 as an embodiment of the free exchange of ideas. Colloquially called Schwangere Auster (Pregnant Oyster).

The Gemäldegalerie contains an astounding array of paintings, including works by Rembrandt, Rubens, Botticelli, Raphael, Titian, Goya, Velasquez and Watteau. The collection contains works from the old Bodemuseum on Museumsinsel in the East, now closed, and the former Gemäldegalerie in Dahlem. Its strong points are German paintings of the 13-16th centuries, Netherlandish painting of the 15th and 16th centuries, Flemish paintings of the 17th century, and miniature paintings of the 16th-19th centuries. In the newer section of the museum, designed by architects Heinz Hilmer and Christoph Sattler, there is enough space to display 1,150 masterpieces in the main gallery and 350 in the studio gallery - of the almost 2,900 pieces in the European painting collections. Established in 1830, the newly built gallery from 1998 has about 7,000 sq m of exhibition space (a complete tour of the 72 rooms covers almost 2 km).

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.

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 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.

A museum dedicated to everyday life in communist East Germany. The museum has very relaxed rules and you are allowed to touch and examine almost every object, which adds greatly to the experience.

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.

An observation tower without an elevator in Southeast Berlin, from which you can see that there is a great deal of forest around Berlin. There is a cafe at the tower.
