Even though it’s only been open for five years, ‘the bunker’ is a fixed destination on Berlin’s art itinerary. Christian and Karen Boros recast the Third Reich colossus as a showcase for curated selections of their 700-odd works beginning in 2007. Appointment-only tours run through the space’s second exhibition (a new group of works was hung last September, with this exhibition being a bit more low-key than the first), which features plenty of hometown talent: Klara Lidén, Wolfgang Tillmans, Michael Sailstorfer and newcomers Awst & Walther all figure large this time around. 

Then again, so does Ai Weiwei. In a converted pumping station across town, Christian (who runs part of his ad agency from there) also spearheads Distanz Verlag, a publisher churning out high-quality art books at “two a week”. Meanwhile, Karen has been heading the VIP programmes for Art Basel’s various iterations since 2005.
