Bianca Maria Visconti

Pada tanggal 24 Oktober 1441 Francesco Sforza dan Bianca Maria Visconti melangsungkan pernikahan di dalam Biara San Sigismondo, Cremona, bukan di Katedral untuk alasan-alasan keamanan. In the typical Italian Renaissance manner, feasts lasted for several days and included a sumptuous banquet, tournaments, a palio, allegorical carts and a huge cake reproduction of the Torrazzo, the city's main tower. It is probable that this cake is the origin of the torrone.
