It is a commercial gallery designed in the XIXth century by Giuseppe Mangoni, very well-known in Italy for his clothes shops, many of them luxury establishments, and with fantastic bookshops and exquisite bars. In the centre of the Gallery there is an enormous mosaic with the figure of a bull. If you place your heel on the bull´s testicles and spin round, it is supposed to bring you good luck!
It is placed in the Piazza del Duomo.
