The relief sculpture Friede sei mit Dir (German: [ˈfʁiːdə ˈzaɪ mɪt ˈdiːɐ̯]), also known as the cock of Berlin is an artwork by sculptor Peter Lenk. It is located in Berlin at the former building of the editorial staff of German newspaper taz. The sculpture displays living persons who were involuntarily used in controversial headlines by newspaper Bild. The main part is a caricature of former Bild editor-in-chief Kai Diekmann, stretched over five floors. The title on the top floor, "Friede sei mit Dir", is a double entendre: either "Peace be with you" or "Friede be with you", the latter referring to Bild's publisher who is depicted on the left-hand side of the fourth-floor façade snake-charming.The sculpture's background is a satirical article and the ensuing lawsuit. In 2002, journalist Gerhard Henschel claimed that Kai Diekmann had undergone a failed medical enhancement operation. Dieckmann sued, unsuccessfully, for damages to his personality rights. The court held that the claimant, in his function as chief editor of Bild, had willingly decided to become an actor in a personality-rights-infringing business from which he was profiting economically, and therefore was not entitled to maximum protection against infringement of his own rights.The sculpture itself was installed in 2009 and remains legally unchallenged.

The Kreuzberg Tower and Wings are a complex of three buildings, designed by the American architect John Hejduk. Located close to Checkpoint Charlie, the project was completed in 1988, shortly before the Berlin Wall came down in 1989. It is considered an iconic work of 20th-century architecture, and one of very few that Hejduk realised during his lifetime.

The Freedom Memorial (German: Freiheitsmahnmal) was a memorial to the victims of the Berlin Wall in the vicinity of the Checkpoint Charlie Museum in Berlin. It opened on October 31, 2004, and was praised by both victims of the GDR communist regime and human rights advocates alike. In 2004, Alexandra Hildebrandt leased an empty lot near the site of the former Checkpoint Charlie, and installed the Freedom Memorial to the victims of the border forces. While welcomed by many, it was criticized by Berlin officials as being historically and symbolically inaccurate, and for being erected by a private individual without a public process. The following year, the lease was terminated by the land owner, a bank. Hildebrand refused to clear out the monument, and the crosses which made up the memorial were removed by bailiffs following a court order.

The Checkpoint Charlie Museum (German: Das Mauermuseum – Museum Haus am Checkpoint Charlie) is a private museum in Berlin. It is named after the famous crossing point on the Berlin Wall, and was created to document the so-called "best border security system in the world" (in the words of East German general Heinz Hoffmann). On display are the photos and related documents of successful escape attempts from East Germany, together with the escape apparatus: hot-air balloons, getaway cars, chairlifts, and a mini-U-boat. The museum researches and maintains a list of deaths at the Berlin Wall. It is operated by the Mauermuseum-Betriebs gGmbH, and the director is Alexandra Hildebrandt.

The Berlin Observatory (Berliner Sternwarte) is a German astronomical institution with a series of observatories and related organizations in and around the city of Berlin in Germany, starting from the 18th century. It has its origins in 1700 when Gottfried Leibniz initiated the "Brandenburg Society of Science″ (Sozietät der Wissenschaften) which would later (1744) become the Prussian Academy of Sciences (Preußische Akademie der Wissenschaften). The Society had no observatory but nevertheless an astronomer, Gottfried Kirch, who observed from a private observatory in Berlin. A first small observatory was furnished in 1711, financing itself by calendrical computations. In 1825 Johann Franz Encke was appointed director by King Frederick William III of Prussia. With the support of Alexander von Humboldt, Encke got the King to agree to the financing of a true observatory, but one condition was that the observatory be made accessible to the public two nights per week. The building was designed by the well-known architect Karl Friedrich Schinkel, and began operating in 1835. It now bears the IAU observatory code 548. Although the original observatory was built in the outskirts of the city, over the course of time the city expanded such that after two centuries the observatory was in the middle of other settlements which made making observations very difficult and a proposal to move the observatory was made. The observatory was moved to Potsdam-Babelsberg in 1913 (IAU observatory code 536). Since 1992 it is managed by the Leibniz Institute for Astrophysics Potsdam (AIP), although it has not been used for German astronomical observations since the 20th century. In Berlin remain the Wilhelm Foerster Observatory (IAU code 544), the Archenhold Sternwarte, Berlin-Treptow (Archenhold Observatory; IAU code 604), the Urania Sternwarte (Urania Observatory, IAU code 537), and the Bruno H. Bürgel Observatory.

The Deutsches Currywurst Museum was a museum in Berlin dedicated to German currywurst sausage.

Checkpoint Charlie (or "Checkpoint C") was the best-known Berlin Wall crossing point between East Berlin and West Berlin during the Cold War (1947–1991), as named by the Western Allies.East German leader Walter Ulbricht agitated and maneuvered to get the Soviet Union's permission to construct the Berlin Wall in 1961 to stop emigration and defection westward through the Border system, preventing escape across the city sector border from East Berlin into West Berlin. Checkpoint Charlie became a symbol of the Cold War, representing the separation of East and West. Soviet and American tanks briefly faced each other at the location during the Berlin Crisis of 1961. On June 26, 1963, U.S. President John F. Kennedy visited Checkpoint Charlie and looked from a platform onto the Berlin Wall and into East Berlin.After the dissolution of the Eastern Bloc and the reunification of Germany, the building at Checkpoint Charlie became a tourist attraction. It is now located in the Allied Museum in the Dahlem neighborhood of Berlin.
