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 art, architecture, and governance. The Viscontis established the Duchy of Milan and were influential in the development of the Sforza dynasty. Their legacy includes the construction of notable landmarks, such as the Castello Sforzesco, and their patronage of artists like Leonardo da Vinci. The family's rule ended in the 15th century, but their impact on Milan's history remains significant.
