Seven subway stations of the German capital’s U7 subway line recently were declared protected buildings as important examples of post-war modernity. Anyone with a subway ticket, which costs about $3, can take a 2-hour tour of Berlin’s post-modern subterranean gallery. Eighty-eight of Berlin’s 173 subway stations are now protected.
The protected stations can still be refurbished, in cooperation with the conservation office, or for instance have elevators added to make them barrier-free.
The U7 line has 40 subway stations, and at 19.8 miles, is the longest subway line in Berlin.
