The Visconti family was a powerful noble family that ruled the city of Milan and its surrounding territories in northern Italy during the late Middle Ages. They rose to prominence in the 13th century and played a significant role in the political and cultural landscape of the region. The family is known for its contributions to the arts and architecture, including the construction of the Castello Sforzesco. The Visconti dynasty produced several notable figures, including Giovanni Visconti, who became the Archbishop of Milan, and Filippo Maria Visconti, who expanded the family's influence. Their rule ended in the 15th century when the Sforza family took over, marking a significant shift in Milanese power dynamics.
