The Neptune Fountain in Berlin was built in 1891 and was designed by Reinhold Begas. The Roman god Neptune is in the center. The four women around him represent the four main rivers of Prussia at the time the fountain was constructed: the Elbe (with the allegorical figure holding fruits and ears of corn), Rhine (fishnet and grapes), Vistula (wooden blocks, symbols of forestry), and Oder (goats and animal skins). The Vistula is now entirely in Poland, while the Oder forms the border between Germany and Poland.

The Rotes Rathaus (Red City Hall) is the town hall of Berlin, located in the Mitte district on Rathausstraße near Alexanderplatz. It is the home to the governing mayor and the government (the Senate of Berlin) of the state of Berlin. The name of the landmark building dates from the façade design with red clinker bricks.

Ampelmännchen, literally little traffic light man, diminutive of Ampelmann is the symbol shown on pedestrian signals in Germany. Prior to German reunification in 1990, the two German states had different forms for the Ampelmännchen, with a generic human figure in West Germany, and a generally "male" figure wearing a hat in the East.

Founded about 1200, the Nikolaiviertel (Nicholas' Quarter) of Alt-Berlin, together with nearby Cölln, jointly make up the reconstructed historical heart of the German capital of Berlin. It is located in Mitte locality (in the homonymous district), five minutes away from Alexanderplatz.

The St. Nikolai-Kirche, (Nikolaikirche or St. Nicholas' Church) is the oldest church in Berlin, the capital of Germany. The church is located in the eastern part of central Berlin, the borough of Mitte. The area around the church, bounded by Spandauer Straße, Rathausstraße, the River Spree and Mühlendamm, is known as the Nikolaiviertel 'Nicholas quarter', and is an area of restored medieval buildings (in some cases recent imitations). The church was built between 1220 and 1230, and is thus, along with the Church of Our Lady at Alexanderplatz not far away, the oldest church in Berlin.

The Humboldt Forum is a museum of non-European art on the Museum Island in the historic centre of Berlin. Named in honour of the Prussian scholars Wilhelm and Alexander von Humboldt, it combines three rebuilt baroque façades of the former Royal Palace, a contemporary exterior overlooking the Spree river and a modern interior designed by Franco Stella. Considered as the "German equivalent" of the British Museum, the Humboldt Forum will mainly house the non-European collections of the Berlin State Museums, temporary exhibitions and public events.
