Visconti Castle (Pavia)

The Visconti Castle of 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.
