Viktoriapark

Theatre that features all plays/music theatre in English.

Like Oranienstraße a street full of shops, cafes and restaurants, but in the other, more middle-class part of Kreuzberg.

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.

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.

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.

Though the area has changed a lot, the building with the Meistersaal, an old music hall from the 1900s, has persisted. Later converted into sound studios, music history was written here with David Bowie ("Heroes"), Iggy Pop, and U2 amongst the groups who recorded here at the "Studio by the wall". Guided tours available occasionally.
