The Priamar Fortress is a fortress occupying the hill with the same name above the port of Savona. The fortress was built in 1542 by the Republic of Genoa on a promontory where in medieval times was the nucleus of Savona, by design of architect Giovanni Maria Olgiati. However, traces of pre-Roman, Roman and Byzantine presences in the site have been excavated in the past centuries, and are now on display in Savona's Archaeological Museum.
In the 17th century the fortress received bastions designed by the Spanish Royal engineer Domenico Sirena, and in the 18th century were added the commissar's, officers' and Sibilla palaces. In order to create space for the new structures, edifices of the medieval Savona, including its cathedral (built in the 9th century over a pagan temple), were demolished.
In 1746, in the course of the War of Austrian Succession, it was stormed by the Piedmontese grenadiers. In 1820, after the annexion of Liguria to Piedmont, it became a prison. During the Risorgimento, Italian patriot Giuseppe Mazzini was jailed in the Priamar Fortress.
The fortress, which could house up to 500 prisoners, remained Italy's main military prison until 1903, when its role was taken by the castle of Gaeta.
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.
