The sculpture park An der Wied in Tennenlohe is a small outdoor art stop on the edge of Erlangen. It places contemporary works in a green, semi-rural setting rather than in a formal gallery.
It is a selective POI: worthwhile if you are nearby, cycling through Tennenlohe, or interested in public art. Do not treat it as one of Erlangen's main sights, but it adds texture beyond the university and Baroque centre.
