Neptunbrunnen

Gothic church, the second oldest (built in late 13th century) of the historical centre of Berlin. It's the highest church tower of Berlin (about 90 m), but seems rather small beneath the gigantic TV tower. The church tower was built in the late 18th century by Carl Gotthard Langhans, the architect of the Brandenburg Gate.

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.

At 368 metres, the Fernsehturm is Berlin's tallest and indeed EU's second-tallest building, complected between 1965 and 1969. The main function of the building is television broadcasting, but the shiny sphere atop the tower houses a viewing platform, a restaurant and a Berlin Tourist Information point. The viewing platform sits 203 metres above ground, affording views of as much as 42 km away and featuring a bar. Given how flat Berlin is, it's not a very interesting view however and the state of the glass means that you can't get good photos either. The Sphere restaurant at 207 metres rotates at a speed of one full spin per 30 minutes. There are two lifts from the base to the platform and cafe, taking 40 seconds to reach the top, as well as a 986-step staircase. The Fernsehturm is not accessible to wheelchair users.
Not all of the Berliners liked the tower and the overall composition of the Alexanderplatz afforded by the socialist city planners. East German T.V. tried to establish the nickname "Telespargel" ("television asparagus") which however doesn't seem to have caught on. During certain times of day, sunlight reflecting from the top caused a large cross-shaped light to shine down on the city. Called the Rache des Papstes (Pope's revenge) by nominally atheist East Berliners, the light-cross was an ironic result of socialist architecture. Rumour has it the architect was deprived of more than his next commission after that fiasco. At night, the Fernsehturm sometimes appears to be shooting light beams from the tower section, giving the impression it's a Death Star à la Star Wars.

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.

Berlin's oldest church (1230) is a 3-nave hall church. It is in the centre of an area destroyed by bombs in the war which was then turned into a faux "old town" by the East German authorities called Nikolaiviertel. The area is more a hodge-podge of relocated buildings than an authentic reproduction, and the newly-built 1988 apartments that attempt to "harmonize" with the older buildings are embarrassing. The church is one of the only structures that was renovated rather than rebuilt. It is best known for a sandstone sculpture called the Spandauer Madonna (1290), but there are other interesting pieces here. When the church was destroyed in 1938 and rebuilt in the 1970s, the communist officials intended to use it as a museum, which did not open until 1987. The museum includes sacred textiles and religious sculpture from the fourteenth to the sixteenth centuries. The Nikolaikirche is the showplace of the Nikolaiviertel, which isn't saying much.

Started in the 15th century and finished in the mid-18th century, the baroque palace was the residence of electors, kings and emperors until 1918, when it became a museum. The palace was badly damaged during World War II and later razed in 1950, replaced by the GDR with a modernist Palast der Republik. The Palast was in turn gradually dismantled at the turn of the century, as it was discovered to contain asbestos and its former function of housing the GDR parliament became obsolete. Berlin has started in June 2013 construction on a new version of its historic Stadtschloss. The Schlüterhof, an inner courtyard, was also rebuilt. The building opened with a delay in 2021 with museums inside and a roof terrace with a good view. Among the Berlin museums this is perhaps the most controversial due to reconstruction of a monarchist palace being seen as a questionable political statement and due to the fact that many of the exhibits were sourced from German colonies under ethically questionable circumstances leading to demands to return some or all of them to their places of origin.
