A very good reason to travel West: the C/O, next to the formerly infamous Berliner Zoo tube station, is an awesome museum dedicated to photography and visual media. Previous exhibitions include Larry Clark, Martin Parr, Anton Corbijn, Annie Leibovitz and Stephen Shore.
25 years ago my father used to work here. I know they have a garden on top of the roof. It looks like a big spaceship, I love the futuristic design it has so many little details, I never get tired looking at it.
