Fantamilano
If we take this map of Milan of the sixteenth century (whose shape is similar to a decagon) and imagine to identify some couples of sides of this decagon as in the figure, we get a bitorus. Exhibit of matemilano (in the section "Topology"), realized by Michele Ciribifera and Stefano Bonacci.
