Blue church, Berlin

Right next to the remnants of a bombed-out church, a new one has been built using blue glass walls that give the entire sanctuary into a luminscent blue glow. You'll find the church near the Berlin Zoo.

Berlin colonnades

Berlin is a conflicted city, trying to decide which parts of its history to erase from memory and which parts to preserve. These colonnades are the subject of public debate over whether to patch over the bullet holes from Russian/Nazi fighting at the end of World War II, or leave them there for their historic value. I vote for leaving them there.

Berlin graffiti

Berlin was front and centre in the graffiti movement, and it shows. The city's got graffiti everywhere, but it adds more of an artistic touch than the usual urban scrawls. Graffiti-watchers will especially enjoy the views from the metro.

Jewish memorial at Berlin

Building a Jewish memorial in Berlin was obviously something of a tricky proposition. The artist created cement slabs of varying sizes and had intended for people to right their thoughts about the Jewish Holocaust on the slabs, but that plan was scrapped when everyone realized the disastrous potential of something like that. So the slabs are blank, creating shadowy corridors for wandering in and out of.
