Humboldt University of Berlin (German: Humboldt-Universität zu Berlin, abbreviated HU Berlin) is a public research university in the central borough of Mitte in Berlin, Germany. It was established by Frederick William III on the initiative of Wilhelm von Humboldt, Johann Gottlieb Fichte and Friedrich Ernst Daniel Schleiermacher as the University of Berlin (Universität zu Berlin) in 1809, and opened in 1810, making it the oldest of Berlin's four universities. From 1828 until its closure in 1945, it was named Friedrich Wilhelm University (German: Friedrich-Wilhelms-Universität). During the Cold War the university found itself in East Berlin and was de facto split in two when the Free University of Berlin opened in West Berlin. The university received its current name in honour of Alexander and Wilhelm von Humboldt in 1949.The university is divided into nine faculties, including its medical school shared with the Free University of Berlin, has a student enrollment of around 32,000 students, and offers degree programmes in some 189 disciplines from undergraduate to postdoctorate level. Its main campus is located on the Unter den Linden boulevard in central Berlin. The university is known worldwide for pioneering the Humboldtian model of higher education, which has strongly influenced other European and Western universities.It was regarded as the world's preeminent university for the natural sciences during the 19th and early 20th century, as the university is linked to major breakthroughs in physics and other sciences by its professors, such as Albert Einstein. Past and present faculty and notable alumni include 57 Nobel Prize laureates (the most of any German university by a substantial margin), as well as eminent philosophers, sociologists, artists, lawyers, politicians, mathematicians, scientists, and heads of state; among them are Albert Einstein, Karl Marx, Friedrich Engels, Otto von Bismarck, W. E. B. Du Bois, Angela Davis, Arthur Schopenhauer, Georg Wilhelm Friedrich Hegel, Walter Benjamin, Max Weber, Georg Simmel, Karl Liebknecht, Ernst Cassirer, Heinrich Heine, Eduard Fraenkel, Max Planck and the Brothers Grimm. As one of Germany's most prestigious institutions of higher education, Humboldt University of Berlin has been conferred the title of "University of Excellence" under the German Universities Excellence Initiative.

The Alexander von Humboldt Memorial to the right of the Humboldt University main building on Unter den Linden avenue in Berlin's Mitte district commemorates the Prussian polymath and natural scientist Alexander von Humboldt (1769–1859). Created in 1882 by Reinhold Begas in neo-baroque style, the marble statue is a masterpiece of the Berlin school of sculpture.

The equestrian statue of Frederick the Great is an outdoor monumental sculpture in cast bronze at the east end of Unter den Linden in Berlin, honouring King Frederick II of Prussia. It was commissioned by Frederick's great nephew, Frederick William III, and dedicated by Frederick's great-great nephew, Frederick William IV. Designed in 1839 by Christian Daniel Rauch and unveiled in 1851, it influenced other monuments. It is a registered monument of the City of Berlin. Beneath the equestrian statue itself, the unusually large plinth includes reliefs of the four cardinal virtues and important scenes from Frederick's life, and depictions, many in full relief, of 74 notable men from his reign; bronze plaques beneath the bands of sculpture list military men, philosophers, mathematicians, poets, statesmen, engineers, and others important in Prussia's emergence as a great power in the mid-18th century.

The Old Palace (German: Altes Palais), also called Kaiser Wilhelm Palace (Kaiser-Wilhelm-Palais), is a former Royal Prussian residence on Unter den Linden boulevard in Mitte, the historic heart and city center of Berlin. It was built between 1834 to 1837 by order of Prince William of Prussia, who later became German Emperor William I, according to plans by Carl Ferdinand Langhans in Neoclassical style. Damaged during the Allied bombing in World War II, the Old Palace was rebuilt from 1963 to 1964 as part of the Forum Fridericianum. Since then, the listed building has been home to the Law Faculty of the Humboldt-Universität.

The Bebelplatz (formerly and colloquially the Opernplatz) is a public square in the central Mitte district of Berlin, the capital of Germany. The square is located on the south side of the Unter den Linden boulevard, a major east-west thoroughfare that runs through Berlin's city center. It is bounded to the east by the State Opera building (hence its prewar name), to the west by buildings of Humboldt University, and to the southeast by St. Hedwig's Cathedral, the first Catholic church built in Prussia after the Reformation. Following the war, the square was renamed after August Bebel, a founder of the Social Democratic Party of Germany.

The Empty Library (1995), also known as Bibliothek or simply Library, is a public memorial by Israeli sculptor Micha Ullman dedicated to the remembrance of the Nazi book burnings that took place in the Bebelplatz in Berlin, Germany on May 10, 1933. The memorial is set into the cobblestones of the plaza and contains a collection of empty subterranean bookcases. It is located in the centre of Berlin next to the Unter den Linden. The memorial commemorates 10 May 1933, when students of the National Socialist Student Union and many professors of the Friedrich-Wilhelms-Universität (today Humboldt-Universität) under the musical accompaniment of SA- and SS-Kapellen, burnt over 20,000 books from many, mainly Jewish, communist, liberal and social-critical authors, before a large audience at the university's Old Library and in the middle of the former Kaiser-Franz-Josef-Platz (1911–1947), now Bebelplatz.

The Alte Bibliothek (English: Old Library), nicknamed Kommode (Commode), is a listed building on Bebelplatz in the historic centre of Berlin. It was erected by order of Frederick the Great from 1774 to 1780 according to plans by Georg Christian Unger and Georg Friedrich Boumann in Baroque style. Older plans by Joseph Emanuel Fischer von Erlach for St. Michael's Wing of Vienna Hofburg served as a basis for the first freestanding library building of Berlin. Damaged during the Allied bombing in World War II, the former Royal Prussian Library was rebuilt from 1963 to 1969 as part of the Forum Fridericianum. Since then, the Alte Bibliothek has been home to the Law Faculty of the Humboldt-Universität.

The Lindentunnel is a partially filled tunnel under the boulevard Unter den Linden in the Berlin district of Mitte. Built from 1914 and opened on December 17 and 19, 1916, the tunnel was used by the tramway as an underpass under the boulevard, replacing an at-grade crossing at the same location that had been put into operation in 1894. The tramway used the structure until 1951, after which it was used as a prop warehouse for the Berlin State Opera and as a parking lot for vehicles of the East German People's Police. After German reunification, performance artist Ben Wagin used parts of the tunnel as an exhibition space, while other parts have been used since the 1990s to store props for the Maxim Gorki Theater. Complete demolition of the tunnel is planned in the medium term.
