The Castello Baradello is a military fortification located on a 430 m high hill next to the city of Como. The castle occupies the ancient site of Comum Oppidum, the original settlement of Como, dating from the 1st millennium BC. Later it was one of the last Byzantine strongholds in the area, surrendering to the Lombards in 588. The castle was restored during the War of the Lombard League, with the help of emperor Frederick Barbarossa (1158). Barbarossa officially donated it to the citizens of Como in 1178.
Napoleone della Torre died here in 1278, having been imprisoned here by Ottone Visconti after the Battle of Desio; his nephew Guido was able to escape in 1283, as well as his brothers Corrado and Enrico the following year. Azzone Visconti restored and enlarged the fortification after conquering Como in 1335, and built another castle, the Castello della Torre Rotonda ('Castle of the Round Tower', now lost) and a citadel.
In 1527, by order of emperor Charles V, the castle was dismantled, with the exception of the tower, to prevent it from falling in hands of the French troops that had invaded the duchy of Milan. After belonging to monks and then to private individuals, the castle was restored in 1971.
The most preserved element is a square tower. It once had Guelph-type merlons. The walls are of Byzantine origin (6th-7th century); these were later heightened and provided with Guelph merlons, while another external line of walls was added.
Also from the 6th century are the Chapel of St. Nicholas and quadrangular tower, which was used as the castellan's residence. Napoleone della Torre was buried in the Chapel of St. Nicholas.
References:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
