The Visconti Castle in Pavia was built in 1360 by Galeazzo II Visconti, soon after the taking of 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.
There are some significant proofs of the great frescoes showing battles, hunting and middle-class life scenes, which decorated rooms, porches and loggias. Another excellent proof is the complete decoration of the splendid Blue Room with its gold and lapislazuli. Perhaps it was the seat of the Visconti library with its 1.000 manuscripts and commissioned by Petrarch.
It presently houses the Civic Museums of Pavia (Museo Civici di Pavia) including 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.
References:Celje Castle was once the largest fortification on Slovenian territory. The first fortified building on the site (a Romanesque palace) was built in the first half of the 13th century by the Counts of Heunburg from Carinthia on the stony outcrop on the western side of the ridge where the castle stands. It had five sides, or four plus the southern side, which was a natural defence. The first written records of the castle date back to between 1125 and 1137; it was probably built by Count Gunter. In the western section of the castle, there was a building with several floors. Remains of the walls of this palatium have survived. In the eastern section, there was an enclosed courtyard with large water reservoirs. The eastern wall, which protects the castle from its most exposed side, was around three metres thicker than the rest of the curtain wall. The wall was topped with a parapet and protected walkway.
