As you walk along the runway from the Herrfurthstrasse entrance towards the terminal, you'll spot community gardens to your left with improvised sculptures built from recycled materials, a circus school abutting an artists' workspace and a biergarten to your right. Closer to the terminal, an 18-piece interactive art installation doubles as a mini-golf course. Round the 4.3-mile loop and you're likely to see people downing pilsners in the re-wilded meadow and unicyclists plying the runway.
