150-200 m along the Wiener Straße (bypassing the fire house and the public swimming pool) from U-Bahn Görlitzer Bahnhof, the park is famous for the Turkish families barbecuing on summer weekends, failed contemporary art and relaxed atmosphere of students. It does have a reputation of being full of pickpockets and drug dealers though and the police makes regular visits to this place to check on the situation.
Take a stroll for a few kilometers along this canal which runs right through the heart of Kreuzberg. It's peaceful and mostly traffic-free, but full of life in summer. Some parts are lined with bars and restaurants with terraces. Sit on a bench or terrace and watch the world go by on a summer evening.
With the Kreuzberg, a hill in Kreuzberg 61, the Prussian National Monument by Schinkel and a waterfall. Superb panoramic views across south Berlin.
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.
Designed by Daniel Libeskind with an excellent exposition on the Jewish life in Berlin and the impact of the Holocaust. You can easily spend a day here. There is a metal scanner and other security features you'd rather expect at an airport than a museum.
It was a museum of applied arts and a listed historical monument since 1966, and it is now a well-known Berlin exhibition hall.
Huge technical museum, on a former railroad depot, featuring from ancient water and wind mills to computer pioneer Konrad Zuse's inventions, a collection of old to new vehicles of all types -bicycles, boats, trains, etc - and the interactive Spectrum science center with various hands-on experiments. There's an actual C-17 "Candy Bomber" airplane hanging on its façade. The railroad and aeronautical sections are hard to beat.
The longest stretch of the Berlin Wall still in existence, painted by artists in 1991 and restored in 2009, after years of decay. At Mühlenstraße, next to the river Spree. The murals are painted on the east side of the wall after the fall of Communism; so they are not from the Cold War, during which murals could only be painted on the west side. Make sure not to miss the famous mural of a car seemingly crashing through the wall with Leonid Brezhnev and Erich Honecker kissing above it. It is actually on the back side of the gallery (it is facing away from the street.) It is just inside the entrance of the Eastern Comfort Hostel, near the east end of the gallery.
Exhibition of digital interactive entertainment culture. You can actually play almost all of the exhibits making it a more "hands on" museum than most.
Arguably the most beautiful bridge in Berlin and the only connection between Friedrichshain and Kreuzberg. As signage on the bridge indicates, it was built twice - once in the 1890s and once in the 1990s. Before reunification the border ran where the bridge now is.
The main street of former East Berlin. It is a big avenue, featuring neoclassical East German buildings, fountains and lakes.
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.
Oderberger Straße is known for its beautiful and generous Gründerzeit architecture, as well as its cafés and restaurants. Since before Germany's reunification the street has been the desired place for alternative folks and avant-gardists, but the area has seen continual gentrification since the early 2000s.
The first (and one of the biggest) water tower of Berlin (built 1877).
The synagogue in the backyard of an apartment house is one of the biggest in Germany.
