An open-air museum with no opening hours? On Mannheim's "Kunstmeile", you can admire works by contemporary artists as you stroll by. Spread along the boulevard "Augustaanlage" are more than 60 sculptures by renowned contemporary artists. The way to this open air museum is pointed by "Die große Mannheimerin", a 13-metre-high sculpture by Franz Bernhard, which can be found at the Planetarium.
