MIC in Bolzano
One of the ten signposts of the MIC project "Maths in the city".
This one is placed in Streiter street, near the fountain of the fish market, and it remarks that the central element of this fountain is a braid, identical to the central element of a bretzel.
You can see another one of the ten signposts.
