Königsstädtisches Theater was the name of different theater buildings in Berlin in the 19th and 20th century. The first Königsstädtisches Theater was built by Carl Theodor Ottmer in Königsstadt, a former settlement neighboring Berlin that is today part of the boroughs of Mitte, Prenzlauer Berg and Friedrichshain, and opened in 1824. Its first director was Karl Friedrich Cerf, who managed it until his death in 1845. An Aktiengesellschaft from its inception, the theater had to rely on financial support by the King of Prussia. When the monarchy stopped its support in 1840, the theater fell on hard times. Involvement in the German revolutions of 1848–49 meant that the theater was closed in 1851 by royal decree.Cerf's son, Rudolf Cerf, had inherited the license and the name from his father, and named the building used by Circus Renz "Königsstädtisches Theater" from 1852 to 1854. The license then was sold to Franz Wallner, a popular actor, who used the name for his own Wallner-Theater until 1858. In the following years, a number of different theaters used the name but none achieved any lasting success. The original theater building was used for various purposes after its closure. It was demolished in 1932.

The Sportvereinigung Dynamo (German: Sportvereinigung Dynamo ) (Dynamo Sports Association) was the sport association of the security agencies (Volkspolizei, Ministry for State Security, fire department and customs) of former East Germany. The association was founded on 27 March 1953 and was headquartered in Hohenschönhausen in East Berlin. From the date of its inception, the permanent president of SV Dynamo was the Minister of State Security Erich Mielke. The Minister of State Security served as First chairman of the association, while the Minister of the Interior served as the Second chairman of the association. The financial and material resources of the SV Dynamo were almost exclusively provided by the Ministry of State Security. Erich Mielke was dismissed as First chairman in December 1989. His position was not replaced. SV Dynamo was dissolved in 1990.Dynamo was set up following the multi-sports club model developed in the Soviet Union and adopted throughout Eastern Europe. From the beginning it had an overtly political as well as sporting agenda and its many successes were always portrayed as a triumph of the German Democratic Republic (GDR). SV Dynamo was dissolved during the Peaceful Revolution. The association had a membership of over 280,000 members at its height. Athletes of the association enjoyed considerable success both in national and international competitions, winning for example more than 200 Olympic medals. After German reunification in 1990 the systematic doping of Dynamo athletes from 1971 until 1989 was revealed by the German media. Doping was done under the supervision of the Stasi and with full backing of the government.

Haus des Lehrers (German for House of the teacher) is a building in Berlin, located near Alexanderplatz, built between 1962 and 1964 under the German Democratic Republic. Its most notable feature is a mural wrapping around the entire building and extending between the second and fifth above-ground floors. Designed in the style of Mexican mural art by artist Walter Womacka, it is titled Unser Leben ("Our Life") and depicts various occupational groups of and aspects of life in the GDR. Adjacent to the building is a two-story congress hall, known since November 2003 as Berliner Congress Center. Between 2003 and 2011, the annual Chaos Communication Congress was hosted there.

Project Blinkenlights was a light installation in the Haus des Lehrers building at the Alexanderplatz in Berlin that transformed the building front into a giant low-resolution monochrome computer screen. The installation was created by the German Chaos Computer Club (CCC) and went online on 11 September 2001 as a celebration of the club's 20th birthday. Some novel uses of the screen are for people to call a number and play Pong via mobile phone or display animations sent in by the public. Similar installations were created by the CCC for the Bibliothèque nationale de France in Paris in 2002 (called Arcade) and for two towers of the City Hall in Toronto (called Stereoscope). Both installations feature higher resolutions and eight shades of grey. In August 2023 a new Installation was shown on the CCCamp in Mildenberg. It was called Polychrome and used RGBw LED which have been calibrated as Tim Pritlove shown in a Talk about the Project on Aug. 16. The electrical engineering and computer science students of the Budapest University of Technology and Economics turn their Schönherz Dormitory into a giant display ("the Matrix") at their annual Schönherz Cup competition, where amongst others, teams compete to create the most interesting and funny animations. A similar display, featuring three colours, is annually created by students of Wrocław University of Technology and the University of Bordeaux,who have released open-source software to create interactive architectural displays. Independently, an installation displaying the message "FERTiG" (German for "FINISHED") was shown at the completion of the Elbphilharmonie in Hamburg in 2016. The term "blinkenlights" originates in hacker humor. One of the CCC installations is depicted in the Golden Boy and Miss Kittin video for their song "Rippin Kittin".

The Battle of Berlin (November 1943 to March 1944) was a bombing campaign against Berlin by RAF Bomber Command along with raids on other German cities to keep German defences dispersed. Air Chief Marshal Sir Arthur Harris, Air Officer Commanding-in-Chief (AOC-in-C) Bomber Command, believed that "We can wreck Berlin from end to end if the USAAF come in with us. It will cost us between 400 and 500 aircraft. It will cost Germany the war".Harris could expect about 800 serviceable heavy bombers for each raid, equipped with new and sophisticated navigational devices such as H2S radar. The USAAF, having recently lost many aircraft in attacks on Schweinfurt, did not participate. The Main Force of Bomber Command attacked Berlin sixteen times but failed in its object of inflicting a decisive defeat on Germany. The Royal Air Force lost more than 7,000 aircrew and 1,047 bombers, (5.1 per cent of the sorties flown); a further 1,682 aircraft were damaged or written off. On 30 March 1944, Bomber Command attacked Nuremberg with 795 aircraft, 94 of which were shot down and 71 were damaged. The Luftwaffe I. Jagdkorps recorded the loss of 256 night fighters from November 1943 to March 1944.The Luftwaffe retaliated with Unternehmen Steinbock (Operation Capricorn) against London and other British cities from January to May 1944. The Luftwaffe managed to assemble a force of 524 bombers but Steinbock caused little damage for the loss of 329 aircraft, a greater percentage loss per raid and overall than that suffered by Bomber Command over Germany.There were many other air raids on Berlin by the RAF, the USAAF Eighth Air Force and Soviet bombers. The RAF was granted a battle honour for the bombardment of Berlin by aircraft of Bomber Command from 1940 to 1945.
