Visconti Park in the context of "Certosa di Pavia"

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.

The Civic Museums of Pavia (Italian: Musei Civici di Pavia) are a number of museums in Pavia, Lombardy, northern Italy. They are housed in the Visconti Castle (Castello Visconteo), built in 1360 by Galeazzo II Visconti, soon after taking the city, a free city-state until then. The credited architect is Bartolino da Novara. The castle used to be the main residence of the Visconti family, while the political capital of the state was Milan. North of the castle a wide park was enclosed, also including the Certosa of Pavia, founded 1396 according to a vow of Gian Galeazzo Visconti, meant to be a sort of private chapel of the Visconti dynasty. The Battle of Pavia (1525), climax of the Italian Wars, took place inside the castle park.

The Civic Museums of Pavia include the Pinacoteca Malaspina, Museo Archeologico and Sala Longobarda, Sezioni Medioevale e Rinascimentale Quadreria dell’800 (Collezione Morone), Museo del Risorgimento, Museo Robecchi Bricchetti, and the Cripta di Sant’Eusebio.
