Galeazzo II Visconti in the context of "Pavia Civic Museums"

Gian Galeazzo Visconti (16 October 1351 – 3 September 1402), was the first duke of Milan (1395) and ruled that late-medieval city just before the dawn of the Renaissance. He also ruled Lombardy jointly with his uncle Bernabò. He was the founding patron of the Certosa di Pavia, completing the Visconti Castle at Pavia begun by his father and furthering work on the Duomo of Milan. He captured a large territory of northern Italy and the Po valley. He threatened war with France in relation to the transfer of Genoa to French control as well as issues with his beloved daughter Valentina. When he died of fever in the Castello of Melegnano, his children fought with each other and fragmented the territories that he had ruled.

Bernabò or Barnabò Visconti (1323 – 19 December 1385) was an Italian soldier and statesman who was Lord of Milan. Along with his brothers Matteo and Galeazzo II, he inherited the lordship of Milan from his uncle Giovanni. Later in 1355, he and Galeazzo II were rumoured to have murdered their brother Matteo since he endangered the regime. When Galeazzo II died, he shared Milan's lordship with his nephew Gian Galeazzo. Bernabò was a ruthless despot toward his subjects and did not hesitate to face emperors and popes, including Pope Urban V. The conflict with the Church caused him several excommunications. On 6 May 1385, his nephew Gian Galeazzo deposed him. Imprisoned in his castle, Trezzo sull'Adda, he died a few months later, presumably from poisoning.

The Visconti Castle of Pavia (Italian: Castello Visconteo di Pavia) is a medieval castle in Pavia, Lombardy, Northern Italy. It was built after 1360 in a few years by Galeazzo II Visconti, Lord of Milan, and used as a sovereign residence by him and his son Gian Galeazzo, first duke of Milan. Its wide dimensions induced Petrarch, who visited Pavia in the fall of 1365, to call it "an enormous palace in the citadel, a truly remarkable and costly structure". Adjacent to the castle, the Visconti created a vast walled park that reached the Certosa di Pavia, a Carthusian monastery founded in 1396 by the Visconti as well and located about 7 kilometres (4.3 mi) to the north.

In the 16th century, an artillery attack on Pavia destroyed a wing and two towers of the castle. The frescos that entirely decorated the castle rooms are today almost completely lost. The castle had been the seat of the Visconti Library until its transfer to Paris in 1499. Today, it hosts the Pavia Civic Museums.

Matteo II Visconti (c. 1319 – 29 September 1355 in Saronno) was co-ruler of Milan together with his brothers Galeazzo II and Bernabò.

Visconti Park (Parco Visconteo in Italian) was the private park of the Visconti and Sforza families, lords, and dukes of Milan. Located in Lombardy, northern Italy, it extended between Pavia Castle and the Certosa di Pavia monastery. It covered an area of about 2,200 hectares (22 km) and was encircled by walls about 25 kilometres (16 mi) in length. It was founded in 1360 by Galeazzo II Visconti and enlarged by his son Gian Galeazzo.

It was used for hunting and as a pleasure ground with various features. Its decay began in 1525 with the damages inflicted during the important Battle of Pavia, which was largely fought (by over 50,000 troops) inside the park. Today, the park's old area is mainly farmland, while some portions are nature reserves.
