Hackesche Höfe

Not far away from Schloss Tegel (at the "große Malche") you can take a look at the oldest tree in Berlin, an oak which has been growing there since about 1192 (so it's actually older than Berlin itself). The name ("fat Mary") allegedly stems from the brother Humboldt who named the tree after their overweight cook.

This heritage-protected public bathing beach which opened in 1907 is one of the largest inland lidos in Europe and has a 1275-m-long sand beach, a capacity for up to 30,000 guests and a popular nudist area.

From 1941, 12,000 tons of concrete in a 15-m-high and 20-m-diameter cylinder were built to test the load-bearing capacity of the Berlin soils (turns out glacial sands are no good basis for gargantuan architecture) for Albert Speer's Germania buildings. Too massive for later blasting, this is one of the more bizarre remains of the Third Reich.

This outdoor and indoor history museum documents the terror applied by the Nazi regime. It is on the site of buildings which during the Nazi regime from 1933 to 1945 were the headquarters of the Gestapo and the SS, the principal instruments of repression during the Nazi era.

A remarkable medium-sized classical castle by the famous K.F. Schinkel built 1820 to 1824, also called "Humboldtschlösschen", because Alexander and Wilhelm von Humboldt (and their family) lived here once. Still privately owned.

The only surviving Berlin city gate and a potent symbol of the city. This is the point where Straße des 17. Juni becomes Unter den Linden. The gate was designed by Carl Gotthard Langhans in 1791 and was intended to resemble the Acropolis in Athens. The Brandenburg Gate now symbolizes reunification, after dividing East and West Berlin for decades. This is the site of Reagan's "Mr. Gorbachev open this gate, Mr. Gorbachev tear down this wall" speech.

Small terrace on the top of the Park Inn, publicly accessible. Take the elevator to the 40th floor, and follow the signs up the stairs. Pay the attendant who also serves beer and coffee. Great views of the Fernsehturm. In the summer, consider base jumping off the roof with Jochen Schweizer. It is often closed in bad/windy weather, so look for a notice posted near the elevator that the terrace is closed.

In 1893 the authorities of Berlin issued the artistic entrance to the National Park Friedrichshain. The fountain of fairy tales was commissioned by the National Park and later designed by Ludwig Hoffmann.

Germany's national centre for contemporary non-European art. The house is a leading centre for the contemporary arts and a venue for projects breaking through artistic boundaries. This architectural landmark was an American contribution to the international building exhibition INTERBAU 1957 as an embodiment of the free exchange of ideas. Colloquially called Schwangere Auster (Pregnant Oyster).

Specializes in 19th-century painting and sculpture; Monet, Manet, Cézanne, C. David Friedrich and other important 18th- and 19th-century artists are well-represented.

Spectacular building by Mies van der Rohe contains its own collection and temporary exhibitions.
